>>IA. Analysis of Solar Active Regions and Activity from 23/2100Z
>>to 24/2100Z: Solar activity has been high. Region 486 (S16E57)
>>produced several flares, including a M7.6/1n at 24/0254 UTC, with an
>>associated Type IV radio sweep. An associated CME was observed on
>>SOHO/LASCO imagery with an estimated velocity of 900 km/s, although

>>produced an M1.3 at 24/1856 UTC. Region 484 appears to be decaying
>>slightly, while Region 486 is growing. Both regions continue to
>>exhibit large, complex beta-gamma-delta magnetic configurations.

>>IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z:
>>The geomagnetic field has been at quiet to severe storm levels. An
>>interplanetary shock was observed at ACE at 24/1450 UTC, with a
>>subsequent sudden impulse observed at 1530 UTC. The sudden impulse
>>was followed by about two hours of severe geomagnetic storm
>>activity, and produced a magnetopause crossing at GOES 12. Solar
>>wind data show high density flow with strong magnetic fields (about
>>30 nT), although so far Bz has been strongly northwards. The greater
>>than 2 MeV electron flux at geosynchronous orbit reached high levels
>>today.
>>
>>IIB. Geophysical Activity Forecast: The geomagnetic field is
>>expected to be at active to severe storm conditions for day one, due
>>to persistence from the current transient-driven activity. Activity
>>should subside to unsettled to minor storm levels on days two and
>>three.
