[Ulrich Rieth]

NOAA 9773, N13W03 (Solar X = 049", Solar Y = 286" at 01/09/17:00 UT) Rapid flux emergence noted yesterday has continued overnight resulting in a complex magnetic delta configuration with a strong gradient and bright H-alpha plage across the delta's magnetic inversion line. We expect C- and M-class events with the possibility of an X-class event.
