Local sky character in Hakonegasaki
Northern mid-latitudes · northern hemisphere · 138 m elevation
- The north celestial pole stands 35.8° above the horizon, so stars within 36° of it never set from here.
- About 79.2% 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 25.2° up, staying low, so a clear southern horizon matters.
- At 138 m elevation, roughly 2% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
Hakonegasaki is small enough that local light domes are limited — on a clear, moonless night the Milky Way is realistically within reach.
