What's in the sky tonight?
October 24, 2014
-The afternoon sun over North America looked a little unusual on Thursday. It was crescent shaped. James W. Young photographed the phenomenon from Wrightwood, California. "What a beautiful eclipse," says Young. "Sunspot AR2192 made it extra special."
Millions of sky watchers in Canada, the USA and Mexico saw the Moon pass in front of the sun, covering as much as 70% of the solar disk over Alaska and as little as 12% over Florida.
-I've also included my own shot of the same sunspot group from my 300mm lens in Toronto, albeit not a impressive of a shot.

As you (safely!) watched the progress of yesterday's partial solar eclipse, you probably also spotted a giant sunspot group. Captured in this sharp telescopic image from October 22nd the complex AR 2192 is beautiful to see, a sprawling solar active region comparable in size to the diameter of Jupiter. Like other smaller sunspot groups, AR 2192 is now crossing the Earth-facing side of the Sun and appears dark in visible light because it is cooler than the surrounding surface. Still, the energy stored in the region's twisted magnetic fields is enormous and has already generated powerful explosions, including two X-class solar flares this week. Coronal mass ejections (CMEs) associated with the flares have not affected planet Earth, so far. The forecast for further activity from AR 2192 is still significant though, as it swings across the center of the solar disk and Earth-directed CMEs become possible.
