BBSO Solar Activity Warning 22-OCT-2003 16:29:02 UT

NOAA 0484,N04E16, Solar X = -266", Solar Y = -018" (10/22/16:30 UT), has entered slow growth phase after displaying very rapid growth since 10/19. 0484 is one of the largest sunspots of the current solar cycle. NOAA 0484 is very complex with an impressive beta-gamma-delta magnetic configuration. C- and M-class events are certain with an X-class event probable. Another region of interest is rotating over the SE limb at about S15. The large sunspot now visible on the limb appears to be positive polarity which would be reversed polarity for the leading sunspot in the southern hemisphere. This new region has produced numerous C- and M-class events and is responsible for several back-sided CMEs. We expect this region to produce C- and M-class events with an X-class event highly probable.

'reversed polarity' - das wäre genial und würde auch die bisherige enorme Aktivität erklären.
