A pair of blasts emerged from the far side of the Sun (July 29-30, 2013). One was a coronal mass ejection from an active region; the other was sparked by a filament eruption (lower of the two). These were identified by reviewing observations from the STEREO spacecraft which are currently able to view the far side of the Sun. Early on July 30 there was another eruption as well. All were captured by SOHO's C3 coronagraph, in which the Sun (represented by the white circle) is blocked out by an occulting disk (center blue disk) so that we can observe faint features beyond that.

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.
