Atos System
The Atos System is the stellar system in which the planet Micras exists. The current model of the system reflects many years of research and synthesis carried out by Bassarid scientists, together with foundational work undertaken by the New Zimian Space Exploration and Settlement Agency, and serves as the standard astronomical framework used in scholarship, cartography, and planetary description.
Overview
The Atos System as it is currently understood, was defined in the early 32.80's PSSC by researchers working for the New Zimian Space Exploration and Settlement Agency. Current models of the Atos System also reflect research completed by scientists in Mercury.
Current scientific questions and theories
Although the broad structure of the Atos System is now treated as established, several major scientific questions remain active. These concern not the existence of the system’s recognized bodies, but the deeper structure of the system itself, the causes of its apparent regularities, and the extent to which its observed order can be explained through ordinary astrophysical models alone.
One especially important field of inquiry concerns the overall coherence of the system. In recent Bassaridian scientific and philosophical writing, some researchers have argued that the Atos System appears unusually ordered in ways not easily reduced to chance accumulation or ordinary long-term disorder.
This line of interpretation has grown especially prominent in connection with the so-called White-Hole Interior Hypothesis, a model developed primarily to explain recurring anomalies associated with Atos itself and with broader system-level regularities.
Within that framework, the Atos System is understood as existing within a bounded interior structured by the Lumen Boundary, a one-way horizon across which energy is held to pass outward but not inward. Proponents of this model argue that such a condition would help account for persistent large-scale coherence across the system, including the endurance of ordered stellar and planetary structures over long durations. In this interpretation, the unusual stability of certain atmospheric, orbital, and ecological systems is not regarded as incidental, but as part of a wider cosmological order maintained by boundary conditions unlike those assumed in conventional astronomical models.
These ideas remain interpretive rather than definitive, and they have not displaced more ordinary astronomical explanations. Even among those willing to discuss the White-Hole Interior Hypothesis seriously, there is no consensus that every unusual or highly ordered feature of the system should be attributed to it directly. Rather, the model has become a framework through which some Bassaridian commentators seek to relate stellar anomalies, planetary regularity, and long-duration environmental stability to one another within a single explanatory structure.
The discovery and subsequent study of living environments beyond Micras and Tarsica have also deepened these debates. The confirmed biosphere of Ampelos, a moon of Thalassa, has become especially important in this regard. Publicly released findings describe Ampelos as a fully life-bearing world with marine and terrestrial life, cold-adapted microorganisms, and an extensive southern subglacial aquatic system. For some researchers, this makes Ampelos one of the clearest examples of the wider structural persistence said to characterize the outer system; for others, it is simply an extraordinary but local case of planetary and biological development under unusual conditions.
For that reason, current scientific discussion of the Atos System increasingly moves along two levels at once. On one level, researchers continue to refine observation, mapping, orbital classification, and comparative study of the system’s many bodies. On another, they explore whether the system’s deeper regularities should be understood as the product of ordinary celestial development, or whether they point toward a larger and still only partially understood cosmological structure. In this sense, the modern study of the Atos System remains not only descriptive, but interpretive.
Bassaridian space exploration
During 53 PSSC, Bassaridia Vaeringheim consolidated its civilian, scientific, and settlement-oriented space activities under the Bassaridian Space Exploration and Settlement Agency (BSESA). The Agency administers the Bassaridian Space Program and serves as the principal Bassaridian institution responsible for the continued exploration, mapping, and eventual settlement of the Atos System.
The establishment of BSESA did not represent the beginning of Bassaridian spaceflight. The Agency inherited the scientific traditions, surviving archives, technical knowledge, and institutional relationships associated with the New Zimian Space Exploration and Settlement Agency and related Bassarid aerospace organizations. Bassaridia Vaeringheim also already maintained an extensive orbital support network around Micras, consisting of active military, commercial, maritime, environmental, navigational, and temple-operated satellites under several different custodians. The General Port of Lake Morovia already functioned as the principal Bassaridian launch, payload-integration, and orbital-logistics centre for this network.
BSESA was therefore formed primarily as an institution of consolidation and expansion. Its purpose was to establish a unified civilian command structure through which existing orbital infrastructure could support dedicated scientific satellites, interplanetary probes, crewed missions, deep-space communications, orbital stations, and permanent settlements beyond Micras. Military and classified orbital systems remain under the authority of the Bassaridian War League, the Somniant Stock Fund, the Hatch Ministry, and other competent institutions, although they may provide tracking, communications, navigation, weather, or emergency support to authorized BSESA missions.
The Agency's external capabilities are strengthened by the Treaty on Spaceflight between the Imperial Federation and Bassaridia Vaeringheim, which provides a framework for access to Imperial launch facilities, testing and assembly services, astronaut training, tracking networks, long-term mission-support facilities, scientific cooperation, and joint missions. The treaty also recognizes the historical association of Bassarid institutions with Alphaville and the former New Zimian space program, including surviving archives, equipment rights, contracts, intellectual property, and institutional relationships.
Within the Atos System, BSESA's early priorities include the consolidation of civilian operations in Micras orbit, renewed exploration of Tarsica, deep-space relay deployment, the survey of Indigo and its satellite system, exploration of the Chryosian Asteroid Belt, scientific and sacred-site research at Chrysos and Heptapolis, the establishment of permanent infrastructure around Thalassa, atmospheric missions to Nephele, Nyktelia, and Morpheia, and eventual expeditions to Glinos, Noctis, Opsithe, and the Opsithian Asteroid Belt.
The Agency also maintains the modern Bassaridian Archive of Discovery, through which orbital observations, planetary maps, surface nomenclature, scientific findings, mission records, samples, and settlement assessments are catalogued. The Bassaridian Cartographic Survey of 53 PSSC forms one of the principal reference works used by the Agency in planning missions and maintaining the standard Bassaridian description of the system.
Bassaridian Cartographic Survey of 53 PSSC
On 54/1/53 PSSC, Bassaridian researchers announced that they had completed the first fully standardized cartographic survey of all major bodies presently recognized within the Atos System. The announcement marked the formal conclusion of a long-running program of planetary and satellite visualization, comparative observation, and regional naming undertaken across the inner worlds, the gas giants, and their principal moons. While earlier Bassaridian and New Zimian research had already defined the broad modern model of the system, the survey of 53 PSSC was the first to present each major body within a unified atlas framework, with regionally organized nomenclature applied according to visible geography, atmospheric structure, and established cosmological association.
The completion of the survey was regarded by Bassaridian astronomers, theologians, and educators as a major intellectual milestone. It did not merely produce a more refined visual reference for the planets and moons of Atos; it also created a coherent system through which the worlds of the system could be described, taught, illustrated, and compared according to a shared Bassaridian standard. In this sense, the survey was as much a work of classification as of observation. It established a common cartographic language for discussing the surfaces, cloud structures, polar systems, fracture belts, impact basins, vortex fields, and transitional regions of the known bodies of the system.
Naming conventions
The regional names assigned during the survey were not chosen arbitrarily. Bassaridian cartographers followed a general principle that each body should receive nomenclature appropriate both to its visible physical character and to the web of cultural, civic, mythological, and religious associations long attached to it in Bassaridian scholarship. Names were therefore selected to reflect a combination of observable geography and inherited symbolic context, while avoiding excessively literal or purely decorative labels. The goal was to produce names that could plausibly function as enduring regional toponyms rather than temporary descriptive captions.
For rocky planets and moons, this meant that named regions generally corresponded to actual surface features visible on the mapped body: broad basins, plains, scarps, shelves, ridges, crater fields, fossae, chasmata, polar caps, and tectonic belts. By contrast, the gas giants received atmospheric nomenclature suited to their visible structure, including crowns, gyres, belts, currents, drifts, reaches, lanes, corridors, vortices, and other terms appropriate to long-lived cloud systems and circulation zones. This distinction was especially important in maintaining a coherent atlas style across bodies as physically different as Eos, Pyros, Noctis, Opsithe, Nephele, Thalassa, and Glinos.
A second principle of the survey was that nomenclature should reflect the particular identity of each world rather than impose one uniform naming style across the whole system. Thus, the names assigned to each body drew selectively upon the body’s established place in Hostianism, the Reformed Stripping Path, civic or cultic institutions associated with it, related Host Star traditions, local festival language, and the historical vocabulary of cities or cult centers especially linked to that world. As a result, the mapping of Nephele drew upon dreamlike, reflective, and cloud-oriented associations; the nomenclature of Glinos emphasized winter, endurance, and cyclical severity; the mapped regions of Opsithe reflected stewardship, cultivation, and seasonal return; and colder bodies such as Noctis were named in a quieter register of secrecy, shadow, humility, and hidden wisdom.
Scope of the completed survey
By the date of the announcement, Bassaridian researchers stated that all major recognized bodies of the system had been brought into the same cartographic framework. This included the star-proximate worlds, the inhabited central bodies, the outer planets, the principal gas giants, and the major moons of those giants. In practical terms, the completed survey extended across Eos, Micras, Tarsica, Pyros, Indigo, Plateau, Momiji, Ivory, Chrysos, Fenrir, Lukedu, Agnis, Thalassa, Styx, Faun, Silenus, Nephele, Cato, Sisera, Erasmus, Glinos, Nikolaj, Noctis, and Opsithe.
The survey established a common and authoritative frame of reference for Bassaridian astronomical description. It consolidated earlier system models into a single standardized presentation and fixed the principal bodies of the system within a unified cartographic order. Nevertheless, within Bassaridian usage the survey of 53 PSSC became the standard frame of reference for maps, illustrations, instructional material, and subsequent descriptive writing on the planets and moons of the system.
Significance
The importance of the completed atlas lay in more than visual polish. It gave Bassaridian scientific and religious scholarship a common descriptive framework through which cosmology, theology, pedagogy, and planetary observation could be brought into closer alignment. It also strengthened the interpretive role of Bassaridia Vaeringheim within Atos-system studies by making Bassaridian cartographic conventions difficult to separate from the now-standard visual presentation of the system.
For Bassaridian scholars, the completed survey demonstrated that the bodies of the Atos System could be understood not only as isolated astronomical objects, but as a connected and interpretable order. Each world could now be discussed in terms of distinct regions, each region in relation to visible structure, and each named structure in relation to the broader symbolic and scientific traditions through which Bassaridian civilization understood the cosmos. In that respect, the cartographic survey of 53 PSSC was not merely a technical achievement, but one of the clearest expressions of the Bassaridian attempt to bind observation, naming, and meaning into a single cosmological discipline.
System architecture and orbital hierarchy
The Atos System is not best understood as a simple linear list of planets, but as a nested orbital structure composed of primary worlds, satellite systems, and two major minor-body regions. In Bassaridian usage, this hierarchy is especially important because it clarifies which bodies are primary planets orbiting Atos, which are moons orbiting those planets, and which smaller bodies belong to the system's two recognized asteroid belts.
The innermost recognized planet is Eos, which orbits closest to Atos. Beyond it lies Micras, the principal inhabited world of the system, accompanied by its moon Tarsica. Farther outward is Pyros, followed by Indigo, which occupies a particularly complex position in the system's orbital structure. Indigo is orbited directly by Plateau and by Momiji, while Momiji is itself orbited by Ivory. This gives the Indigoan system a layered hierarchy in which one moon possesses a subordinate satellite of its own.
Beyond the inner rocky and temperate worlds lies the Chryosian Asteroid Belt, extending approximately from 1.33 to 1.86 astronomical units from Atos. The belt forms the principal transitional region between the compact inner planets and the giant outer bodies. Bassaridian astronomers have long treated it not merely as a scattering of minor objects, but as a distinct structural division of the system containing rocky, metallic, and carbon-rich bodies of widely varying size and composition.
Past the Chryosian Asteroid Belt stands Chrysos, the innermost of the giant planets in the standard system model. It is orbited by the moons Fenrir, Lukedu, and Agnis. Beyond Chrysos is Thalassa, whose recognized moons include Styx, Faun, Silenus, Ampelos, and the other satellites listed on Thalassa's page. Farther outward still is Nephele, orbited by Cato, Sisera, and Erasmus. Beyond Nephele lies Glinos, accompanied by Nikolaj.
Near the outer edge of the planetary system are the distant bodies Noctis and Opsithe, which are treated as independent outer planets rather than satellites of any larger world. Beyond the orbit of Opsithe begins the Opsithian Asteroid Belt, a broad outer population of icy planetesimals, cometary bodies, dwarf-world candidates, and smaller fragments extending approximately from 16 to 35 astronomical units from Atos.
The Opsithian Asteroid Belt differs substantially from the warmer and predominantly rocky Chryosian Asteroid Belt. Its objects are believed to contain large quantities of water ice and other frozen volatile compounds preserved under the extremely cold conditions of the outer system. The inner portion of the belt contains the majority of its comparatively stable and moderately inclined objects, while its outer margins gradually merge into a more dispersed population of bodies possessing eccentric or highly inclined orbits.
Current models generally attribute the broad structure of the Opsithian Asteroid Belt to the combined long-term influence of the outer planets and to changes in their orbits during the early development of the Atos System. Because Opsithe is considerably less massive than the giant planets, the belt is not believed to have been shaped by Opsithe alone. Its present organization is instead understood as the surviving product of planetary migration, gravitational scattering, collisions, and the gradual removal of unstable bodies.
This hierarchical arrangement is useful not only for astronomy, but also for cartography and education. It allows the bodies of the Atos System to be discussed as related planetary and satellite systems bounded and separated by two compositionally distinct minor-body regions: the inner Chryosian Asteroid Belt and the distant Opsithian Asteroid Belt.

Opsithian Asteroid Belt
The Opsithian Asteroid Belt is the outermost major minor-body region presently recognized within the Atos System. Beginning beyond the orbit of Opsithe, it extends from approximately 16 to 35 astronomical units from Atos. The name reflects the belt's position beyond Opsithe rather than any assumption that the planet directly governs or contains its constituent bodies.
Unlike the comparatively warm and predominantly rocky Chryosian Asteroid Belt, the Opsithian Asteroid Belt is composed chiefly of extremely cold, volatile-rich objects. These include irregular planetesimals, cometary nuclei, fragmented rubble bodies, and several objects regarded as possible dwarf worlds. Water ice is believed to be widespread, together with frozen methane, ammonia, carbon compounds, and other substances that could not remain stable across much of the inner Atos System.
The belt is not uniformly dense. Its inner and central regions contain a comparatively stable population of bodies following moderately eccentric and low-to-intermediate-inclination orbits. Beyond this region, the population becomes increasingly dispersed, with objects occupying eccentric, inclined, or otherwise dynamically disturbed paths. Some researchers therefore distinguish between the principal Opsithian Belt and a wider trans-Opsithian scattered population, although the precise boundary between the two remains debated.
Bassaridian astronomers regard the belt as a reservoir of material preserved from the earliest formation of the Atos System. Its study is expected to provide evidence concerning the original composition of the system's protoplanetary disc, the migration of the outer planets, and the origin of many long-period and returning comets. The belt has consequently become an important destination for long-range probes, although its distance, low temperatures, widely separated bodies, and lengthy orbital periods make systematic exploration difficult.
No indigenous life has been confirmed within the Opsithian Asteroid Belt. Nevertheless, its volatile-rich bodies are regarded as important astrobiological targets, particularly in searches for complex organic compounds, dormant microorganisms, or evidence that material capable of supporting life was transported inward during the early history of the system.
Overview of Chryosian Asteroids
The following is a list of the largest catalogued asteroids found within the Chryosian Asteroid Belt, which divides the Inner Atos System from the Realm of the Gas Giants. Most of these bodies take their names from Bassaridianism, one of Micras' most important religious traditions. One asteroid is named after the celebrated Craitish footballer Freddie Gaärsen, while another is named for the alcoholic beverage produced from the national fruit of Craitland. No equivalent catalogue of major Opsithian bodies has yet been completed.

Astrobiology
The study of life within the Atos System has become one of the most important areas of modern planetary science. For much of the history of system research, Micras and Tarsica were treated as the only known life-bearing worlds. Tarsica in particular came to be recognized not merely as a barren satellite, but as a moon with a thin yet persistent atmosphere, a limited hydrological cycle, and a small but genuine biosphere. f In 46.87 PSSC, researchers associated with the New Zimian Space Exploration and Settlement Agency announced the discovery of Bijarids, large single-celled organisms inhabiting the system’s major Chryosian Asteroid Belt and feeding on rock and dust. This discovery was of major scientific importance because it established that life in the Atos System was not confined solely to the Micras–Tarsica pair, and that even the apparently hostile environment of the belt could sustain a distinct and highly unusual biological form.
Later probe observations made the Bijarids still more significant to astrobiologists. Although they are not generally described as intelligent in the conventional sense, repeated encounters with automated probes passing through the Chryosian Asteroid Belt toward the Outer Atos System have suggested a limited but notable capacity for environmental awareness. Several probes have recorded Bijarids altering their movement patterns, clustering around unfamiliar objects, and remaining near active instruments for extended periods before dispersing. Bassaridian researchers have cautiously described this behavior as investigative or exploratory, while emphasizing that it may represent a sophisticated form of chemotactic, electromagnetic, or vibrational response rather than conscious curiosity. Even so, the apparent ability of Bijarids to distinguish probes from ordinary rock, dust, and debris has made them one of the most unusual known life-forms in the system.
Subsequent developments broadened this picture considerably. Ampelos, one of the lesser moons of Thalassa, is now publicly described as a life-bearing world with a confirmed and established biosphere. Released findings state that the moon supports not only microorganisms, but marine and terrestrial plant life, multicellular animals, and complex subsurface aquatic life beneath its southern ice.
These disclosures have made Ampelos the clearest known example of a living world elsewhere in the system beyond Micras and Tarsica, and one of the most important objects in modern Atos-system astrobiology.
As a result, astrobiological discussion of the Atos System now proceeds on several levels at once. Micras remains the principal inhabited world; Tarsica demonstrates that a small satellite sustains a genuine though limited biosphere; the Chryosian Asteroid Belt reveals that life may arise in highly unconventional forms under extreme conditions; the observed behavior of Bijarids raises questions about the boundary between simple responsiveness and primitive intelligence; and Ampelos shows that even an outer moon of a gas giant may possess a stable hydrological cycle and a complex living environment.
Together, these discoveries have significantly expanded the scientific understanding of where life may exist within the system and under what conditions it may endure.
Known Bijarid colonies
Although individual Bijarids are usually described as single organisms rather than social animals, probe surveys have identified several persistent aggregations within the Chryosian Asteroid Belt. Bassaridian astrobiologists commonly refer to these aggregations as Bijarid "colonies," though the term is used cautiously: it does not imply settlement, tool use, or organized intelligence, but rather repeated clustering of large semi-translucent organisms around the same families of carbon-rich asteroid fragments, dust streams, and rubble fields.
These colonies are significant because they appear to be more stable than ordinary temporary feeding clusters. In most recorded cases, Bijarids disperse after exhausting a local mineral surface or after probe activity ceases. The colonies listed below, by contrast, have been observed across repeated survey passes, usually in the same broad orbital neighborhoods. Their persistence has made them useful biological reference points for later Chryosian Asteroid Belt surveys, especially where the organisms appear to respond to active instruments, electromagnetic emissions, surface vibration, or chemical residue left by automated probes.
| Colony designation | Belt region | Associated asteroid band | Approximate location | Description |
|---|---|---|---|---|
| Known Bijarid colonies of the Chryosian Asteroid Belt | ||||
| Euphrosyne Mantle Reef | Inner belt | Euphrosyne | Near the inner margin of the belt, around the Euphrosyne orbital neighborhood, roughly between 1.47 and 1.55 AU from Atos | A broad aggregation attached to carbon-rich fragments near the inner belt. Probe images describe the colony as a pale, semi-translucent mantle spreading across exposed rock faces, with darker mineral inclusions visible beneath its membrane-like outer surface. Its position near the belt's inner edge makes it one of the first Bijarid concentrations encountered by probes travelling outward from the inner planets. |
| Agave Dust Bloom | Inner-middle belt | Agave | Within the Agave orbital band, close to the compact 1.56–1.57 AU region | A bright, dust-feeding concentration found among high-inclination debris associated with Agave. The colony is noted for forming diffuse lobes around fine particulate streams rather than remaining fixed to a single large fragment. Surveys report repeated clustering around active instruments, making it one of the best-known examples of Bijarid probe-responsive behavior. |
| Tar Umbra Mat | Central belt | Tar | In the darker Tar-adjacent rubble fields, broadly around 1.55–1.59 AU | A low-albedo colony occupying shadowed basaltic and carbonaceous fragments. Unlike the paler Euphrosyne and Agave colonies, the Tar Umbra Mat is difficult to distinguish from surrounding rubble except when backlit or chemically stimulated. Bassaridian researchers often cite it as evidence that Bijarids can adapt their visible surface coloration to local mineral environments. |
| Melusine Carbon Lattice | Middle-to-outer belt | Melusine | In the Melusine region near 1.68 AU | A lattice-like aggregation distributed through a relatively compact debris family. Rather than forming one continuous mat, the Melusine colony appears as linked patches across multiple fragments. Its repeated reformation after probe disturbance has led some astrobiologists to suggest that Bijarids may maintain chemical or electromagnetic continuity across short gaps of dust and vacuum-exposed debris. |
| Thyrsus Veil | Outer belt | Thyrsus | Along the broad Thyrsus corridor, roughly between 1.66 and 1.84 AU | A loose veil-like colony spread across a wide orbital zone. It is less dense than the inner colonies, but covers a larger region of dusty debris and broken stone. Probe records describe multiple translucent sheets or lobes drifting among fragments, suggesting a feeding pattern adapted to diffuse dust concentrations rather than large exposed asteroid surfaces. |
| Redquill Outer Filament | Outer rim of the belt | Redquill | Near the outer edge of the Asteroid Belt, around 1.87 AU | A thin filamentary colony marking the outer biological limit of regular Bijarid observations. Its position near the transition toward the Realm of the Gas Giants makes it useful as a biological waypoint for probes travelling outward. The Redquill colony is generally less massive than the inner colonies, but is notable for its persistence in a colder and more weakly illuminated region of the belt. |
The distribution of these colonies suggests that Bijarids are not spread evenly throughout the Asteroid Belt. They appear most commonly where carbon-rich fragments, fine dust, and fractured mineral surfaces occur together, and where orbital conditions allow feeding surfaces to remain available over long periods. Their concentration around named asteroid bands also indicates that the largest asteroids and their associated debris families may serve as ecological anchors within the belt.
The existence of persistent Bijarid colonies has deepened the debate over the organisms' responsiveness. Some researchers interpret the colonies as simple feeding zones, maintained by mineral availability and passive chemotaxis. Others argue that their repeated clustering around probes, their apparent reformation after disturbance, and their tendency to remain near active instruments point toward a more complex sensory capacity. Even the more cautious interpretation, however, treats the colonies as among the most important astrobiological sites in the Atos System, since they demonstrate that life in the belt is not merely present, but regionally structured.
Star Maps
In 45.55 PSSC, the New Zimian Space Exploration and Settlement Agency announced that it had completed its efforts to map the night sky. Soon after, in 45.70, it announced that it had determined the approximate location of the Atos System within its respective galaxy.
The New Zimian Space Exploration and Settlement Agency estimates that there are approximately 23,732,367 stars which are observable from Micras. A list of the largest and brightest stars is as follows. Note that the star images were captured with the aid of highly powerful telescopes. Many smaller stars which can be seen in these images, cannot be observed with the naked eye.
Stars are named for historical and mythological figures in the Pallisican, Bassarid and Alperkin religious traditions. All names are derived from the Simplified Pallisican Language.
Northern Hemisphere
The northern sky of Micras is dominated by a dense and symbolically important concentration of bright stars, many of which occupy a central place in Bassarid, Pallisican, and Alperkin cosmological tradition. In Bassaridian astronomical usage, the northern hemisphere is often treated as the more ceremonially prominent half of the visible sky, owing in part to the brightness and cultural importance of stars such as Azos and Danaß. The northern chart shown above corresponds to the upper star map and illustrates the principal naked-eye stars and major bright objects visible from the northern latitudes of Micras.
The stars listed below are arranged according to the northern celestial sphere as observed from Micras. Their mapped positions, brightness, and associated imagery reflect the standardized star survey completed by the New Zimian Space Exploration and Settlement Agency, and later incorporated into Bassaridian instructional and cosmological usage.

Southern Hemisphere
The southern sky of Micras presents a distinct celestial field, with its own bright stars, positional structure, and inherited symbolic associations. Although often discussed less frequently in northern-centered ritual and educational contexts, the southern hemisphere remains an essential part of the full mapped sky and preserves many stars of great visual and interpretive significance. The southern chart shown above corresponds to the lower star map and represents the principal bright stars visible from the southern latitudes of Micras.
Taken together with the northern chart, the southern field completes the standardized division of the Micrasian night sky into two major observational hemispheres. The stars listed below form part of the same wider celestial order, but are grouped separately in order to reflect their visibility, position, and practical use in southern-sky observation.
