NOAA 9393 remains a worthly candidate with the potential to produce another major flare before west limb passage. The effects from the flare activity from AR9393 on the 29th of March produced a nice Aurora seen here lasr night at 10:00 pm local Big Bear time. Auroras are rare in Southern California! The position of AR9393 on March 31st at 16:30 UT: N17W39 (Solar_X = 580", Solar_Y = 362")

NOAA 9393, N17W25 (Solar_X = 390", Solar_Y = 350") on March 30th at 16:30 UT, retains a complex magnetic configuration and bright H-alpha plage. C- and M-class events are certain with the possibility of another X-class event before west limb passage.

NOAA 9393, N17W15 (Solar_X = 226", Solar_Y = 335" at 16:30 UT on March 29th) produced several M-class flares yesterday and today and the X1.7 event today at 10:15 UT. AR9393 remains in growth phase and continues to have the potential to produce M-class events and another X-class event.

NOAA 9393, N17W01 on March 28/16:30 UT (Solar_X = 016", Solar_Y = 389") continues to be a worthly candidate for M-class events with the possibility of producing an X-class event as well.

BBSO Solar Activity Warning 27-MAR-2001 17:27:55 UT
NOAA 9393 located at N18E12 (Solar_X = -191, Solar_Y = 402) on March 27/16:30 UT continues in strong growth phase. This large plage complex includes NOAA 9401 (located just east - N22E34 - and contiguous with AR9393). We expect a high-level M-class event with a good chance of an X-class event as well.

BBSO Solar Activity Warning 26-MAR-2001 17:19:48 UT
NOAA 9393 located at N19E25 (Solar_X = -386", Solar_Y = 410") on March 26/16:30 UT has developed significantly since yesterday. AR9393 displays a large delta configuration with new flux emerging just SW of the original sunspot. The new flux has formed an additional delta configuration. AR9393 has produced several C- and low-level M-class events. We expect C- and M-class activity to continue with an increasing chance for an X-class event.
