Arching Eruptive Prominence (June 12, 2002)

  • Higher resolution version (TIF,5.4M)
  • A long, arching, solar prominence in extreme ultraviolet light (ionized helium at 304Å) is seen erupting from the Sun on 9 June 2002. This is certainly one of the largest prominences ever observed by SOHO. Prominences are huge clouds of relatively cool, dense plasma suspended in the Sun's hot, tenuous corona. Magnetic fields built up enormous forces that propelled particles out beyond the Sun's surface. Emission in this spectral line shows the upper chromosphere at a temperature of about 60,000 degrees K. For a sense of scale, the prominence extends over approximately 50 Earths from end to end. A fleeting phenomenon, it had disappeared by the time the next image in this wavelength was taken about 6 hours later.

    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.
