Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 172 Issued at 2200Z on 20 Jun 2008
IA.  Analysis of Solar Active Regions and Activity from  19/2100Z
to 20/2100Z:  Solar activity was at very low levels.  Region 999
(S02E06) has remained stable over the summary period.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
at very low levels.
IIA.  Geophysical Activity Summary 19/2100Z to 20/2100Z:
The geomagnetic field was at mostly quiet to unsettled levels.  There
was an isolated period of active conditions observed from 0300 -
0600Z on 20 June, due to sustained southward Bz and elevated wind
speeds.  The greater than 2 MeV electron flux at geosynchronous
orbit reached high levels.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at predominately quiet levels for the forecast period
(21 to 23 June).
