Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 209 Issued at 2200Z on 27 Jul 2008
IA.  Analysis of Solar Active Regions and Activity from  26/2100Z
to 27/2100Z:  Solar activity was very low. No flares were observed.
The visible disk remained spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 26/2100Z to 27/2100Z:
Geomagnetic field activity was at quiet levels. The greater than 2
MeV electron flux at geosynchronous orbit was high.
IIB.  Geophysical Activity Forecast:  Geomagnetic field activity is
expected to be at quiet levels during most of the period (28 - 30
July). However, there is a chance for unsettled levels early on 28
July.
