A supermoon is the coincidence of a full moon or a new moon with the closest approach the Moon makes to the Earth on its elliptical orbit, resulting in the largest apparent size of the lunar disk as seen from Earth.

In 2016 there were three consecutive supermoons (in October, November and December). The moon on November 14 was the closest supermoon since January 26, 1948.
