DECEMBER SOLSTICE: Tonight is the longest night of the year in the Northern Hemisphere and the shortest night in the Southern Hemisphere. The December Solstice, which marks the change of seasons, occurs at 12:30 a.m. on the 22nd EST (9:30 p.m. on the 21st PST) when the Sun reaches its farthest point south on the celestial sphere. Happy Solstice! THE SUN IN A BEER CAN: "I have captured the sun in an empty beer can," reports Jan Koeman of Kloetinge, the Netherlands. In June 2011, Koeman assembled a solargraph--a simple pinhole camera consisting of a beer can lined with photographic paper--and for the past six months he has used it to record the sun's daily motion across the Dutch sky. Today he removed the photo-paper for inspection: 6-month Solargraph How-to Guides: spaceweather.com/

SEASON IN A BEER CAN: Jan Koeman of the Netherlands has captured an entire season in a single beer can. On June 21st, Koeman assembled a solargraph--a simple pinhole camera consisting of a beer can lined with photographic paper--and throughout the summer of 2012 he used it to record the sun's daily motion across the Dutch sky. On Sept. 21st, he removed the photo-paper for inspection: "As you can see, the summer wasn't too bad at all!" says Koeman. "There was lots of sunshine in the backgarden of my parents in Middelburg." Next up: Autumn in a beer can. Stay tuned. Solargraph How-to Guides: #1, #2, #3 www.spaceweather.com/
