Local sky character in Sepatan
Tropical / equatorial latitudes · southern hemisphere · 11 m elevation
- The south celestial pole stands 6.1° above the horizon, so stars within 6° of it never set from here.
- About 55.3% of the whole sky rises above the horizon at some point in the year from this latitude.
- The Milky Way's core in Sagittarius culminates about 67.1° up, clearing the horizon haze comfortably.
- The Large Magellanic Cloud only reaches about 26.4° altitude, so it is a low, seasonal target rather than a year-round one.
- At 11 m elevation, roughly 0% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
Sepatan is a town-scale settlement, so the edge of the built-up area is often dark enough for the Milky Way on moonless nights.
