Courtesy Mark RyanThe skies over Minneapolis cleared yesterday just in time to see last night's supermoon. So-called supermoons occur when the Moon is at the closet point (perigee) in its elliptical orbit around Earth during a full moon phase. The Moon at that position can be up to 14% closer and 30% brighter than a full moon at apogee (at its farthest point in Earth orbit). In astronomy circles, supermoons are known as "perigee full moons", and aren't really as rare as recent media reports have been making last night's event out to be. A supermoon occurs about once every 14 full moons in a full moon cycle. The last supermoon was just last month (but this month's was the biggest of the year). The next supermoon will be in August of 2014, and one of the largest supermoons in a long time to come will take place in November of 2016. The shot seen was taken last night from the bridge on the west side of Lake of the Isles. The top of the Uptown Theater's marquee tower can be seen beneath the lunar disk.
