Supermoon tonight

Spaceweather ( says:

“BE ALERT FOR SUPERMOON HALOS: Tonight’s full Moon is the biggest and brightest of 2018.  It’s a perigee “supermoon”–as much as 8% wider and 16% brighter than average full moons later in the year. This means it’s time to be alert for supermoon halos. Tonight’s full Moon is “super” because it occurs at perigee–the side of the Moon’s elliptical orbit closest to Earth. It will be more than 50,000 km closer to Earth than full Moons on the opposite side of the Moon’s orbit, apogee. Supermoons naturally produce super moon halos. Tonight, watch for luminous ringspillars, and dogs around the bright lunar disk–and have a Happy New Year!”
