Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 199 Issued at 2200Z on 18 Jul 2010
IA.  Analysis of Solar Active Regions and Activity from  17/2100Z
to 18/2100Z:  Solar activity was very low.  Region 1087 (N24W48) has
a simple alpha magnetic classification.  A further analysis of the
SOHO/LASCO imagery from yesterday show a CME was observed on C3
imagery which can be correlated with the C2 x-ray flare at 17/1801Z.
This event does not seem to be Earth directed.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low with a slight chance for a C-class flare from Region 1087.
IIA.  Geophysical Activity Summary 17/2100Z to 18/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet levels for the next three days (19-21 July).
