It's time for another highlight in the heavens, with a supermoon on tap for Sunday, when the moon will rise as close to Earth as any full moon this year.

A supermoon, according to astrologer who the coined the term, Richard Nolle, is a new or full moon that comes within 90 percent of the moon’s closest distance to Earth.

Sunday’s supermoon, the brightest and biggest at about 2 p.m. EST, will be about 12 percent wider and 30 percent brighter than at its farthest distance away in January, according to the U.S. Naval Observatory.

It’s the fourth supermoon this year, following one on July 12. The fifth will occur Sept. 9.

Though the difference in the moon’s distance, only about a few hundred miles, is nearly impossible to discern with the naked eye, it causes physical effects like larger-than-usual tides, according to EarthSky.

The moon will continue looking full and bright Sunday evening through early Monday, and the best time to watch the moon from any location is right after sunset. The best photo-taking opportunities are also just following sunset, as an optical illusion makes the moon appear larger when near the horizon.
