Local sky character in Arth
Northern mid-latitudes · northern hemisphere · 425 m elevation
- The north celestial pole stands 47.1° above the horizon, so stars within 47° of it never set from here.
- About 86.6% 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 13.9° up, staying low, so a clear southern horizon matters.
- At 425 m elevation, roughly 5% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
Arth is small enough that local light domes are limited — on a clear, moonless night the Milky Way is realistically within reach.
