  • A growing clique of rather large sunspot groups rotated into view over a period of several days from March 29 to April 2. As of April 2, they were facing right towards Earth and have the potential to be the source of significant solar storms. The largest of these spots is several times the size of Earth. Sunspots are the visible tracers of magnetically active regions. Because they are somewhat cooler (4,000 C) than the rest of the Sun's surface (6,000 C), they appear darker.

    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.
