Local sky character in Atenas
Tropical / equatorial latitudes · northern hemisphere · 704 m elevation
- The north celestial pole stands 10° above the horizon, so stars within 10° of it never set from here.
- About 58.7% 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 51° up, clearing the horizon haze comfortably.
- The Large Magellanic Cloud only reaches about 10.3° altitude, so it is a low, seasonal target rather than a year-round one.
- At 704 m elevation, roughly 8% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
Atenas is small enough that local light domes are limited — on a clear, moonless night the Milky Way is realistically within reach.
