October full moon 2022 guide: The Hunters’ Moon

The full moon of October, called the Hunter’s Moon, will grace the skies on Oct. 9, the same day that the planet Mercury reaches its highest altitude in the pre-dawn sky, and a day after it reaches the greatest elongation (separation) from the sun.

That means on the night of the full moon Mercury will be visible before sunrise and at an altitude high enough to make it easier than usual for observers in mid-northern latitudes.
