Spot Coming Around (June 29, 2007)
Hi-res TIF image (1.6M)
SOHO is keeping a close eye on a good-sized active region that is rotating into view. The video clip covers 36 hours (June 27-28, 2007) as the bright glow and arcs above the solar surface appear before we can actually see a sunspot on the surface of the Sun. The images were taken in extreme ultraviolet light at the 195 Angstrom wavelength. There have not been very many sunspots over the past year or so, so this one is generating some interest among solar observers. The sunspot that preceded it by a few days has generated some modest flares.
Maybe this one will display even more firepower?
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.
