Local sky character in San Juan

Tropical / equatorial latitudes · northern hemisphere · 7 m elevation

The north celestial pole stands 18.5° above the horizon, so stars within 19° of it never set from here.
About 65.8% 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 42.5° up, clearing the horizon haze comfortably.
The Large Magellanic Cloud only reaches about 1.8° altitude, so it is a low, seasonal target rather than a year-round one.
At 7 m elevation, roughly 0% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
