The moon appeared slightly larger and brighter Monday night during what’s known as a Supermoon.
October’s Harvest Supermoon is the first of three this year. It happens when a full moon is closer to Earth in its orbit. That makes the moon look up to 14% bigger and 30% brighter than the faintest moon of the year, according to NASA. The subtle difference happens a few times a year, sometimes coinciding with other astronomical events such as lunar eclipses.
In the latest viewing, the moon will pass within about 224,600 miles (361,459 kilometers) of Earth. The closest Supermoon of the year is slated for November, followed by another in December.
Viewers in the Bay Area were treated to clear skies Monday evening as the full moon rose.
