Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 171 Issued at 2200Z on 20 Jun 2010
IA.  Analysis of Solar Active Regions and Activity from  19/2100Z
to 20/2100Z:  Solar activity has been very low. No flares occurred
during the past 24 hours.  Region 1082 (N27W10) is growing slowly
but was quiet and stable. (Todays 10.7 cm flux was estimated using
RSTN data).
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low with a slight chance for an isolated C-class event.
IIA.  Geophysical Activity Summary 19/2100Z to 20/2100Z:
The geomagnetic field has been quiet. The greater than 2 MeV electron
flux at geosynchronous orbit was at high levels today.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet.
