Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 173 Issued at 2200Z on 21 Jun 2012
IA.  Analysis of Solar Active Regions and Activity from  20/2100Z
to 21/2100Z:  Solar activity was very low.  Region 1504 (S15W89)
produced a long duration B7 flare at 21/1814Z which was the largest
event of the period.  There were no Earth-directed CMEs observed
during the period.
IB.  Solar Activity Forecast:  Solar activity is expected to be
predominantly very low for the next three days.  There is a chance
for an isolated C-class flare from Region 1504 on day 1 (22 June) as
it approaches the west limb.
IIA.  Geophysical Activity Summary 20/2100Z to 21/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit was at high levels throughout the period.
IIB.  Geophysical Activity Forecast:  Geomagnetic activity is
expected to be quiet on 22-24 June.
