Full moon on November 25

It’s the Northern Hemisphere’s Frosty Moon. Flower Moon for the Southern Hemisphere. November full moons follow the path of the sun in May.

The full moon shines in front of the constellation Taurus the Bull. Six months from now - in late May - the sun will be in front of Taurus, and in the vicinity of Aldebaran and the Pleiades star cluster.  The green line depicts the ecliptic - Earth's orbital plane projected onto the dome of sky. Northern US and Canada can watch the moon occult Aldebaran late tonight. Click here for details.

Good night to locate constellation Pisces, behind the moon and Uranus. Then you can search for Pisces again – and maybe find Uranus, too – when the moon moves away.
