ISS Tonight

Dark skies over Rio de Janeiro, Brazil

The next moonless night in Rio de Janeiro is Sat 7 Nov, dark from 19:29 to 03:42. 3 of the next 30 nights have no Moon at all during full darkness.

Dark here means astronomical darkness (the Sun at least 18° below the horizon) with the Moon below the horizon: the best conditions for faint stars, the Milky Way and astrophotography. Light pollution and weather aren’t included.
