There will be a Supermoon December 3 and 4. A Supermoon is a new or full moon that comes close to Earth in its elliptical orbit; this is called a Lunar Perigee.

The full moon comes on December 3 and lunar perigee takes place on December 4.

The best time to observe the Supermoon is when the moon is near the horizon during either moonrise or moonset:

Sunday Evening, Dec. 3 –  Moonrise — 6:15pm
Monday Morning, Dec. 4 – Moonset — 7:56am
Monday Evening, Dec. 4 – Moonrise — 6:57pm
