Local sky character in Ulsan

Northern mid-latitudes · northern hemisphere · 10 m elevation

The north celestial pole stands 35.5° above the horizon, so stars within 36° of it never set from here.
About 79.1% 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 25.5° up, staying low, so a clear southern horizon matters.
At 10 m elevation, roughly 0% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
