As Jeff Hopkins correctly inferred, my post resulted from perusing the current images at the SOHO site: http://sohowww.nascom.nasa.gov/data/realtime/ ...specifically the 'MDI continuum' shot, which is more-or-less a visible-light picture. The four 'EIT' images are at far-ultraviolet wavelengths, and so show the high-temperature activity, particularly now in the two regions coming onto the visible disc. \Brian -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
