ISS TonightDark skies over Ottawa, Canada
The next moonless night in Ottawa is Fri 6 Nov, dark from 18:24 to 05:09. 6 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.
