Space.com reports that on Sun., June 23 the moon will be at perigee, its closest point to Earth. This year it happens as the moon enters its fullest phase, creating the so-called "supermoon." At its fullest and closest, the moon will appear about 12 percent larger in the sky, and up to 30 percent brighter, according to Space.com. Sunday night the moon rises in the evening, and should be visible, weather-permitting, in the WGXC listening area. See Space.com for more information about the supermoon.
