Bortle 2: truly dark sky. Tonight's real sky above it, live.

Calculating the sky…

Drag to turn round. Stars from the HYG catalogue; glow and horizon from the light model and the terrain.

The usual sky here

Bortle 2.

The Milky Way is detailed to the horizon, with its dark lanes; clouds are black holes in the starfield.

Where the light comes from

The brightest glow on the horizon comes from Oulu, 173 km to the south-east.

Each wedge is how much artificial light arrives from that direction (10° slices).

An estimate of the usual sky with no Moon and no clouds, from NASA's night-lights map and a light-propagation model (about ±0.3 mag). A given night depends on the Moon, the clouds, dust and humidity.

When to go

The Moon, night by night

A bright Moon washes out the faint stars. The highlighted nights are the dark ones (less than a quarter lit); below, the next new moons.

Night: Sun more than 18° below the horizon. Milky Way: the galactic centre more than 10° up during that night. Clear sky: 100 − NASA cloud amount (2001–2020). Coldest: average minimum brought to this altitude.

The place

Aavasaksa.

Hill in Ylitornio, Finnish Lapland

Aavasaksa is a mountain in Finland, 242 m above the sea.

Its usual sky, with no Moon or clouds, is estimated at 21.77 mag/arcsec² — Bortle 2, truly dark sky: the naked eye reaches stars of magnitude 6.5.

The nearest town of over 50,000 people is 88 km away.

The best months are from November to February: long dark nights and clearer skies.

From here the core of the Milky Way never rises above the horizon.

Auroras are frequent: this is auroral-oval country.

The horizon is open all round: nothing in the relief rises more than 3°.
