We had to wait until early December for the first supermoon of 2017. 2018 will be much kinder. You won't be waiting even a day. The first supermoon of 2018 lands on January 1.
So, sleep the night before off on New Year's Day and then get outside to enjoy an extra large, extra bright full moon to welcome 2018.
This supermoon is part of a trio coming in rapid succession. The first of the trifecta landed on December 3. The wolf moon (the name for the first full moon of the year) on January 1 will be the second, and the third will be extra special. It comes on January 31 and will be both a blue moon (the second of two full moons in a single month) and a full lunar eclipse.
