Over the year, although we are on the downward slope after having passed the peak of solar activity, solar storms (either solar flares or coronal mass ejections) occur on the Sun almost every day. Most of these are considered rather minor. But strong, visually stunning blasts still occur fairly frequently. Here is a retrospective of nine images from storms taken by the LASCO C2 instrument. Most of these images have never been highlighted before, but, grouped together in this series, one can appreciate the variety, size, and power of these blasts. In all instances with this instrument the Sun is more than blocked out by an occulting disk so that the instrument can see activity in the corona, which is 100 times less bright than the Sun, and perhaps a million times less bright than the Sun when observed from near Earth (where SOHO is).

Previous Picks of the Week

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.
