BBSO Solar Activity Warning 28-MAY-2003 14:47:30 UT

NOAA's 0365, S07W27, Solar X = 428", Solar Y = -099" at 05/28/14:00 UT, produced two X-class events since the BBSO Solar Activity Warning yesterday. The region was first observed as a rapidly developing EFR located just east of spotless region NOAA 0365. The region has continued in rapid growth phase and is now a very large beta-gamma-delta magnetic configuration with a steep magnetic gradient along its unusual E-W magnetic inversion line. The two X-class flares were an X1.3 at 05/27/23:07 UT and an X3.6 at 05/28/00:27 UT. Both X-class flares were observed at Big Bear. This region has the potential to produce C-, M-, and X-class events with the chance of producing an even larger X-class event.
