Tonight's sky above Katsuta, Ibaraki, Japan

Whether tonight is a good night for stargazing from Katsuta, Ibaraki, Japan comes down to four real things: the Moon phase, cloud cover, which planets are up, and the current Kp index.

Local sky character in Katsuta

Northern mid-latitudes · northern hemisphere · 21 m elevation

The north celestial pole stands 36.4° above the horizon, so stars within 36° of it never set from here.
About 79.7% 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 24.6° up, staying low, so a clear southern horizon matters.
At 21 m elevation, roughly 0% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
