Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 172 Issued at 2200Z on 20 Jun 2012
IA.  Analysis of Solar Active Regions and Activity from  19/2100Z
to 20/2100Z:  Solar activity was low.  Region 1504 (S16W77) produced
a C3 flare at 20/1628Z 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 low for the next three days.  There is a slight chance
for an isolated M-class flare from Region 1504 on day 1 (21 June) as
it approaches the west limb.
IIA.  Geophysical Activity Summary 19/2100Z to 20/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels during the period.
IIB.  Geophysical Activity Forecast:  Geomagnetic activity is
expected to be quiet on 21-23 June.
