Local sky character in San Luis
Tropical / equatorial latitudes · northern hemisphere · 381 m elevation
- The north celestial pole stands 16.2° above the horizon, so stars within 16° of it never set from here.
- About 63.9% 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 44.8° up, clearing the horizon haze comfortably.
- The Large Magellanic Cloud only reaches about 4.1° altitude, so it is a low, seasonal target rather than a year-round one.
- At 381 m elevation, roughly 4% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
San Luis is small enough that local light domes are limited — on a clear, moonless night the Milky Way is realistically within reach.
