Local sky character in Mira

Northern mid-latitudes · northern hemisphere · 32 m elevation

The north celestial pole stands 40.4° above the horizon, so stars within 40° of it never set from here.
About 82.4% 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 20.6° up, staying low, so a clear southern horizon matters.
At 32 m elevation, roughly 0% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
