The Punch of a Solar Flare (November 14, 2002)
This LASCO C2 sequence of six consecutive images taken over one and a half hours on 11 November 2002 shows shows the propagation of a coronal mass ejection (CME) associated with a relatively small M1 flare. Flares are intense releases of radiant energy, often associated with violent mass motions such as eruptive prominences and CME's. The bright material in the center of the outward-propagating CME is probably denser, cooler prominence material. The Sun, blocked by an occulting disk, is represented by the white circle. The breadth of view of the instrument is twelve solar radii or about 8.6 million kilometers. This event was probably not strong enough to deliver significant space weather effects on Earth. Although we have passed the Sun's peak period of maximum activity, it remains quite active and is quite capable of producing large geo-effective events.
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 firstname.lastname@example.org.
