Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 182 Issued at 2200Z on 01 Jul 2002
IA.  Analysis of Solar Active Regions and Activity from  30/2100Z
to 01/2100Z:  Solar activity was low. Minor C-class flares were
observed throughout the period. Region 19 (S18E50) now exceeds 600
millionths of white light area with a magnetic delta configuration.
Despite its obvious complexity, this region was relatively quiet.
Region 17 (S19W37) is in a slow growth phase and is developing some
mixing. Another impressive coronal mass ejection was observed off
the SE limb today associated with a prominence eruption at 01/1300Z.
IB.  Solar Activity Forecast:  Solar activity is expected to be low
to moderate. Regions 17 and 19 both have potential for an isolated
M-class flare.
IIA.  Geophysical Activity Summary 30/2100Z to 01/2100Z:
The geomagnetic field was quiet to active. Isolated  minor storm
periods were observed at high latitudes.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to continue at quiet to active levels with isolated minor
storm conditions at high latitudes. These disturbed conditions are
likely to subside by day three.
