Just a reminder, don't miss the 'Supermoon' this weekend! Set to peak on Sunday, June 23, the 2013 supermoon is noteworthy not only for the remarkable sight it will present to skywatchers but also because it will be the largest supermoon this year. The moon will be closest to Earth at 7:32 a.m EDT on June 23, but you will be able to see the supermoon shining bright on Saturday, June 22 as well. Since it's closer to us, the moon appears up to 14 percent bigger and 30 percent brighter than usual.
