Today’s Moon phase, 21 August 2017, Monday is New Moon in Leo ♌
The Moon today is in a New Moon phase. During this phase the Moon is to close to the sun in the sky to be visible. The moon rises and sets with the sun and is not present in the night sky. Because of this the night sky is darker and an excellent time to view other celestial objects. Like the Full Moon, a New Moon happens at a very specific time when the sun and moon have the same ecliptic longitude and it can be measured down to the second it occurs.
