Local sky character in Arlon

Northern mid-latitudes · northern hemisphere · 421 m elevation

The north celestial pole stands 49.7° above the horizon, so stars within 50° of it never set from here.
About 88.1% 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 11.3° up, staying low, so a clear southern horizon matters.
At 421 m elevation, roughly 5% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
