  • 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 304Å) 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.
