The Active Region last seen about 10 days earlier by STEREO (Ahead) has been spotted by the trailing STEREO (Behind) spacecraft (Nov. 9-10, 2009), now more than 60 degrees away from the earth in its orbit around the Sun. It is still quite substantial in size and moderately active, judging by the video clip. Here we see it rotating into view in profile taken in extreme UV light. The region should begin to be visible from the Sun-Earth line by SOHO and ground-based observers from Nov. 13 and after as the Sun carries it around again. It will take almost two weeks to rotate out of view again. Let’s see if it spouts off as many flares as it did last time around. (And note the solar jets spurting out from the solar edge near the bottom of the movie frames.)


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 steele.hill@gsfc.nasa.gov.
