CMEs, Stage Right (April 19, 2013)


Hi-res TIF (1.4M)

Movies: QT: Large ( 12M), Small (1.9M),
MPEG: Large ( 13M), Small (6.8M), MP4 (4.4M)

A coronal mass ejection (CME), associated with a solar flare, sent a cloud of particles to its right out from an active region at it edge, followed by a secondary blast pointed a little lower over about a 24-hour period (Apr. 18-19, 2013). The movie combines images from three instruments on two spacecraft. The originating blast from the Sun was taken by SDO (seen in extreme UV light). This series of frames was superimposed on top of SOHO's C2 (red) and C3 (blue) coronagraph images from SOHO.

The coronagraph images block out the Sun so that the fainter structures out in the corona can be observed. The black, diagonal feature is the strut that holds the disk that occults the Sun in C3. The blast was not likely to impact Earth, but could have some impact on Mercury.

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.
