Rapid Fire Bursts (August 11, 2012)
Hi-res TIF (1.4M)
An active region shot out a number of small flares and bursts that led up to one larger eruption in just one day (Aug. 7, 2012). The region, viewed here in extreme UV light by the STEREO Behind spacecraft, has now rotated around so that it is facing towards Earth. Abrupt changes in the magnetic field near the solar surface drive this activity.
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 firstname.lastname@example.org.
