Tonight's sky above Arth, Schwyz, Switzerland

Local sky character in Arth
Northern mid-latitudes · northern hemisphere · 425 m elevation
- The north celestial pole stands 47.1° above the horizon, so stars within 47° of it never set from here.
- About 86.6% 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 13.9° up, staying low, so a clear southern horizon matters.
- At 425 m elevation, roughly 5% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
Arth is small enough that local light domes are limited — on a clear, moonless night the Milky Way is realistically within reach.

Best nights this month in Arth
Calculated for these coordinates and today's date — not a fixed list.
- 2026-10-21 — Orionids peak — up to 20/hour
Radiant in Orion. Visible from both hemispheres. The Moon is 72% lit on peak night, so lunar interference is moderate.
- 2026-10-25 — Full Moon
A 99%-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.
- 2026-11-05 — Taurids peak — up to 5/hour
Radiant in Taurus. Favours the Northern Hemisphere, which includes Arth, Schwyz, Switzerland. The Moon is 18% lit on peak night, so lunar interference is low.
- 2026-11-09 — 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 Arth, Schwyz, Switzerland.

- Can you see the aurora tonight in Arth, Schwyz, Switzerland?
- Arth, Schwyz, Switzerland is far enough from the pole that aurora only reaches overhead during a major geomagnetic storm — specifically when the planetary Kp index reaches about 6.6, a level reached only a handful of times per solar cycle.
- What is the stargazing light pollution level in Arth, Schwyz, Switzerland?
- Arth, Schwyz, Switzerland is a small town — typically Bortle class 1–4 (rural to excellent dark sky), where the Milky Way is usually visible on clear, moonless nights away from local lighting. These are typical ranges for this population size, not a measured reading for this exact spot — use tonight's Moon phase and the best-nights list above to time a visit away from direct lighting.
- Does Arth, Schwyz, Switzerland's elevation help stargazing?
- At 425 m you are above a meaningful fraction of the atmosphere, which reduces extinction and scintillation — the reason major observatories are sited high. Sphinx Observatory sits about 71 km from Arth, Schwyz, Switzerland at 3571 m.
- What should I plan for observing near Arth, Schwyz, Switzerland?
- High sites reward targets that suffer most from atmosphere: planets at high altitude, faint nebulae, and the Milky Way, which culminates around 13.9° here. Cold and thinner air are the practical constraints, not the sky.
- How dark does it actually get in Arth, Schwyz, Switzerland tonight?
- About 9.8 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.
