Local sky character in Koshimizu

Northern mid-latitudes · northern hemisphere · 19 m elevation

  • The north celestial pole stands 43.9° above the horizon, so stars within 44° of it never set from here.
  • About 84.6% 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 17.1° up, staying low, so a clear southern horizon matters.
  • At 19 m elevation, roughly 0% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
