Local sky character in Arroio dos Ratos
Southern mid-latitudes · southern hemisphere · 70 m elevation
- The south celestial pole stands 30.1° above the horizon, so stars within 30° of it never set from here.
- About 75.1% 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 88.9° up, passing almost directly overhead.
- The Large and Small Magellanic Clouds are circumpolar here — visible on any clear, dark night of the year.
- At 70 m elevation, roughly 1% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
