The video clip of 24 hours of activity and the still (both in partial close-up) show at least two active regions in ultraviolet light (August 9, 2005) that are making clear magnetic connection in profile. Active Regions, like magnets, have north and south polarity. Sometimes a pole of one active region reaches out and connects with the opposite pole of another active region. There is one example of this here. Basically we are observing ions in extreme UV light as they spiral along magnetic field lines. Such connecting and reconnecting occurs constantly on the Sun at all scales of size. It should be noted that most of the magnetic field is invisible, simply because there's insufficient matter at any temperature we can observe entrained in it.

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.
