	Lunar eclipse December 10, 2011 Submitted by: Dennis Anderson at 2011-12-10 23:11:01 The moon was just beginning to exit the darkest part of the Earth's shadow as viewed from near Homer, Alaska around 6:00 a.m. Local time. Very thin clouds were beginning to move in and scattered the light of the brightest portion. The reddish glow of light refracted through Earth's atmosphere is still plainly visible. This was a pretty bright eclipse with the moon glowing a bright reddish orange for about 50 minutes during totality. Copyright (c) Dennis C.

	Multiple but brief arcs - 9 December 2011 Submitted by: Beth Katz at 2011-12-10 03:32:01 Top to bottom: circumzenithal arc, 46 degree halo, upper tangent arc, faint 22 degree halo. There was also a brilliant sun dog on the right and part of the 46 degree halo on the left. The 46 degree halo definitely was not touching the circumzenithal arc above it, so that rules out the supralateral arc. These clouds were very fleeting, and I didn't have time to run into the house and grab my better camera. So these are from my iPhone 3GS. From Lancaster County, Pennsylvania around 3:20pm on 9 December 2011. Sun about 11.5 degree altitude. Copyright (c) 2011 Beth Katz, katz@cs.millersville.edu.

2012-01-27 19:45:00 UTC: N39.3923 W77.5534 - Clear Spring, Maryland, USA

One observer at previously seen northern lights approximately 40-50 times at higher latitudes. The second observer had previously seen them once. A third observer was with us, and we have photos.

2012-01-25 07:22:00 UTC: N41.87 W87.62 - Chicago, IL

Well it's never a total wast of time to make an observation... you also have to learn what ISN'T an aurora and I spent 3 hrs doing that tonight. Observed at Adler Planetarium and North Ave. Beach in Chicago, IL from 10:30PM 24jan12 to 1:30 AM(local time). There was some lake fog and it was hazy - could barely make out the major stars in the Big Dipper. Diffuse light glow in N/NE. Possible occasional appearance of very faint diffuse dark red glow in sky - or was it just an optical illusion? Never could tell for sure.

2012-01-25 03:45:00 UTC: S45.01 E170.6 - Oamaru New Zealand

2012-01-25 03:15:00 UTC: N48 W97.5 - 2 miles east of Manvel, North Dakota

Faint band formed in the north about 15 degrees around 2:30utc. The band brightened and spread as high as 35 degrees. By 3:15utc, the band dissipated. The band reformed to 15 degrees around 4:00utc and at the moment brightening.

2012-01-24 20:00:00 UTC: N53.9803 E11.0288 - Kalkhorst (Germany)

Last night we could detect short episodes of auroral activity by using digital cameras. Our observation was made in a very dark place near the Baltic Sea coast. We could not see the auroral visually. The only structures which were detected arediffuse reddish glow with some structures in form of rays and some movement of those rays. We did expect a much brighter and bigger display, but it did not occur. We had a great evening under a very dark sky with brilliant stars and the milky way, though.
