Huge Eruptive Prominence (February 19, 2002)

  • SOHO observed a huge eruptive prominence arching out from the Sun on Feb. 18, 2001. The first image captured it in extreme ultraviolet light (EIT 304) when part of it had already stretched beyond the instrument's field of view. Here it probably extends more than 50 times the size of Earth. In the second (LASCO C2) image the expanding arch can be seen still largely intact just two hours later as the brightest part of a coronal mass ejection. The solar storm carries billions of tons of particles at millions of kilometers per hour.

    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.
