A supermoon occurs when the moon hits perigee and becomes full at the same time. Perigee is the point on the moon’s orbit when it is closest to the Earth. On average, you can spot a supermoon roughly every 14 months. Today’s, however, is the biggest and brightest occurrence in almost 70 years.

The moon was closest at 8:52 EST this morning, but don’t fret if you missed it. The difference between the view this morning and tonight will be subtle, so don’t forget to get a glimpse tonight. You won’t be able to see one like it until 2034!
