TUCSON – The final Super Moon of the year will be “mostly” visible across SE Arizona tonight. According to Chief Meteorologist Matt Brode there will be plenty of clouds in the sky tonight so visibilty won’t be nearly as good as early versions this year.

A Super Moon is when the elliptical, not circular orbit, matches up with a full moon near its perigee. The perigee is the point of the orbit where the moon is farthest away from the Earth. The result is that the full “super” moon appears slightly larger and slightly brighter in the sky. This occurs about one in every 14 full moons.
