Large Eruptive Prominence (May 15, 2002)
A solar prominence in extreme ultraviolet light (ionized helium at
304Å) is seen rising and pushing away from the Sun on 14 May 2002.
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 about 10 Earths out from the Sun. It had
disappeared by the time the next image was taken about 6 hours later.|
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.
