Local sky character in Rancagua
Southern mid-latitudes · southern hemisphere · 520 m elevation
- The south celestial pole stands 34.2° above the horizon, so stars within 34° of it never set from here.
- About 78.1% 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 84.8° up, passing almost directly overhead.
- The Large and Small Magellanic Clouds are circumpolar here — visible on any clear, dark night of the year.
- At 520 m elevation, roughly 6% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
