Local sky character in Cayey
Tropical / equatorial latitudes · northern hemisphere · 397 m elevation
- The north celestial pole stands 18.1° above the horizon, so stars within 18° of it never set from here.
- About 65.5% 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 42.9° up, clearing the horizon haze comfortably.
- The Large Magellanic Cloud only reaches about 2.2° altitude, so it is a low, seasonal target rather than a year-round one.
- At 397 m elevation, roughly 5% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
Cayey is small enough that local light domes are limited — on a clear, moonless night the Milky Way is realistically within reach.
