Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 172 Issued at 2200Z on 21 Jun 2010
IA.  Analysis of Solar Active Regions and Activity from  20/2100Z
to 21/2100Z:  Solar activity has been very low.  Region 1082 (N27W23)
produced todays only flare, an isolated B1 event at 21/1912Z. A
filament near N19W18 disappeared sometime between 21/0207Z and
21/1200Z, and was associated with a CME on the west limb.
Coronagraph data indicates the CME is not earth directed
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 20/2100Z to 21/2100Z:
The geomagnetic field has been predominately quiet with an isolated
unsettled period at 21/0600-0900Z.  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.
