Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 158 Issued at 2200Z on 07 Jun 2001
IA.  Analysis of Solar Active Regions and Activity from  06/2100Z
to 07/2100Z:  Solar activity was low. Isolated, mostly minor C-class
events occurred during the period. The largest event was an
impulsive, optically uncorrelated C6 flare that occurred at 07/2007
UTC. Most of the day's activity came from Regions 9484 (S06W47),
9488 (S18E04), and 9492 (N19E50). Region 9488 remains the most
magnetically complex region with a beta-gamma magnetic
classification. The rest of the disk and limbs were mostly quiet and
stable.
IB.  Solar Activity Forecast:  Solar activity is expected to be
mostly low. A slight chance of isolated M-class is possible.
IIA.  Geophysical Activity Summary 06/2100Z to 07/2100Z:
The geomagnetic field was at quiet to mostly unsettled conditions.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet to unsettled conditions.
