Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 152 Issued at 2200Z on 01 Jun 2005
IA.  Analysis of Solar Active Regions and Activity from  31/2100Z
to 01/2100Z:  Solar activity was moderate. Region 772 (S18E36)
produced an M1 x-ray flare at 0243 UTC with associated type II
sweep. The region generated numerous C-class events during the day
as well. Data indicate a modest degree of magnetic complexity and
growth in white light. Elsewhere, new region 773 (S12E76) rotated
into view with mature leader and follower spots.
IB.  Solar Activity Forecast:  Solar activity is expected to be low.
Region 772 should continue to produce C-class activity with an
isolated M-class flare possible.
IIA.  Geophysical Activity Summary 31/2100Z to 01/2100Z:
The geomagnetic field was quiet to unsettled. The energetic electron
flux at geosynchronous orbit was high again today.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be unsettled through 04 June.
