Blowing through Space (April 6, 2012)

A week of images from one of two STEREO Heliospheric Imagers on its 'Behind' spacecraft reveals at least half a dozen coronal mass ejections (CME's) blowing out from the Sun and heading into space (Mar. 25 - April 2, 2012). This imager is a wide-angle visible-light imaging system for the detection of CME events in interplanetary space and, in particular, of events directed towards the Earth. In these images and movies the Sun is just to the left of the field of view and the Earth would be millions of miles to the right. The Sun has been busy popping off solar storms like these as it approaches the maximum of its 11 year activity cycle. The period of peak activity is predicted to occur in about a year.

(Note: Mercury is the bright object moving from right to left against the background of stars near the center of the images.)

 

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.
