WASHINGTON (WHDH) - Stargazers, astronomers and curious sky watchers got a chance to witness the first and only supermoon of this year Sunday night.
NASA photographer Bill Ingalls captured photos from Washington, D.C.
Supermoons happen when the sun, moon and earth align, and a full or new moon aligns with the sun’s lunar orbit.
The supermoon tends to be brighter and appear to be larger than its usual size.
The last supermoon happened in November of 2016
Two more will be visible in January.
Astronomers say the best time to catch a glimpse of a supermoon is either right after sunset or minutes before the next sunrise.
