Two for Two (September 17, 2010)

The Sun blasted out two modest-sized coronal mass ejections (CMEs) into space over a two-day period (Sept. 13-14, 2010). SOHO captured the action with its C2 coronagraph in which the sun is blocked out (by the circular occulting disk in the center of the image) to reveal the faint structures in the corona. The white circle represents the size of the Sun. With no apparent eruptions on the Earth-facing side of the Sun, and some signs of events in STEREO Ahead and Behind spacecraft (that observe portions of the Sun which spacecraft like SOHO and SDO cannot), both these events must have been directed away from Earth.
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 email@example.com.
