Tonight's sky above Shimo-tsuma, Ibaraki, Japan
Above Shimo-tsuma, Ibaraki, Japan tonight, the sky is a live system: the Moon's illumination, which planets have cleared the horizon, and whether Earth's magnetosphere is quiet or churning all change hour by hour.
Above Shimo-tsuma, Ibaraki, Japan tonight (36.18°, 139.97°), expect a new moon moon at 0% illumination. The night gives 7.2 hours of true astronomical darkness. At 36.2°, aurora needs a strong storm — roughly Kp 9 or higher — to reach Shimo-tsuma, Ibaraki, Japan.
Local sky character in Shimo-tsuma
Northern mid-latitudes · northern hemisphere · 28 m elevation
- The north celestial pole stands 36.2° above the horizon, so stars within 36° of it never set from here.
- About 79.5% 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 24.8° up, staying low, so a clear southern horizon matters.
- At 28 m elevation, roughly 0% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
Shimo-tsuma is small enough that local light domes are limited — on a clear, moonless night the Milky Way is realistically within reach.

- 2026-08-13 — Darkest night of the coming month
The Moon is only 0% illuminated, giving the least lunar interference in the next 30 nights — the best window for the Milky Way and faint deep-sky targets from Shimo-tsuma, Ibaraki, Japan.
- 2026-08-28 — Full Moon
A 100%-lit Moon washes out faint objects, but lunar terrain along the limb is at its most striking — plan bright targets and planets instead of deep sky.
Shimo-tsuma, Ibaraki, Japan stargazing questions
- What can I see in the sky tonight from Shimo-tsuma, Ibaraki, Japan?
- Tonight from Shimo-tsuma, Ibaraki, Japan expect a new moon Moon at 0% illumination, with these naked-eye planets above the horizon after dark: Venus, Jupiter, Mercury, Saturn, Mars. The night offers about 7.2 hours of true astronomical darkness.
- Does Shimo-tsuma, Ibaraki, Japan's elevation help stargazing?
- At 28 m you are above a meaningful fraction of the atmosphere, which reduces extinction and scintillation — the reason major observatories are sited high. Nobeyama Radio Observatory sits about 137 km from Shimo-tsuma, Ibaraki, Japan at 1350 m.
- What should I plan for observing near Shimo-tsuma, Ibaraki, Japan?
- High sites reward targets that suffer most from atmosphere: planets at high altitude, faint nebulae, and the Milky Way, which culminates around 24.8° here. Cold and thinner air are the practical constraints, not the sky.
- How dark does it actually get in Shimo-tsuma, Ibaraki, Japan tonight?
- About 7.2 hours of astronomical darkness (Sun more than 18° below the horizon). That is the real observing window for faint objects; brighter targets are workable from dusk onward.
