While many witnessed an almost full moon Saturday night, the so-called "supermoon" reached the point in its orbit that is closest to Earth early Sunday, making the evening moonrise prime-time viewing for supermoon 2013.

During supermoon, the moon appears larger on the horizon next to trees and buildings creating an optical illusion where the moon appears 14 percent larger than normal, according to the Associated Press.
In Chicago, the ideal viewing time was 7:40 p.m. Sunday, though moonset may enable another stellar view.
Many Chicagoans took to social media to share their supermoon moments, with some of them gathered below. To catch up on supermoon photos and experiences from around the globe, check out the HuffPost supermoon blog.
