Halo CMEs Galore (October 5, 2012)


Hi-res TIF (3.4M)

Movies: QT (large) (102M), QT (small) (4.6M), MP4 (5.0M), M4V (2.0M)

The Sun produced four halo coronal mass ejections (CMEs) in just three days as well as several other eruptions (Sept. 27-29, 2012). Halo CMEs are called that because the leading edge of the particle clouds appears to expand in a circle around the Sun. The source of the CME was either near the center of the Sun on the front side (facing Earth) or the far-side. Three of the halo CMEs were determined to be from the far-side. The one early on September 28th originated from an active region on the front-side. The video clip was taken by the LASCO C3 instrument with frames every 12 minutes.

 

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.
