Local sky character in Koster
Southern mid-latitudes · southern hemisphere · 1620 m elevation
- The south celestial pole stands 25.9° above the horizon, so stars within 26° of it never set from here.
- About 71.8% 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 86.9° up, passing almost directly overhead.
- The Large and Small Magellanic Clouds are circumpolar here — visible on any clear, dark night of the year.
- At 1620 m elevation, roughly 17% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
Koster is small enough that local light domes are limited — on a clear, moonless night the Milky Way is realistically within reach.
