Active Region Worth Watching (November 5, 2010)
Hi-res TIF image (1.5M)
While old active region 1112 is just rotating into view on Nov. 5 for the Solar Dynamics Observatory, the STEREO (Behind) spacecraft was in position (almost 90 degrees behind Earth's orbit around the Sun) to watch it in extreme ultraviolet light as it produced several smaller flares (Nov. 3, 2010). It will be numbered 1121. One flare produced a quick flash around noon during this video clip and also sent out several waves of plasma across part of the Sun's surface. It could be a solar storm producer as it comes to face Earth more directly over the next few days.
SOHO began its Weekly Pick some time after sending a weekly image or video clip to the American Museum of Natural History (Rose Center) in New York City. There, the SOHO Weekly Pick is displayed with some annotations on a large plasma display.
If your institution would also like to receive the same Weekly Pick from us for display (usually in Photoshop or QuickTime format), please send your inquiry to email@example.com.
