Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 205 Issued at 2200Z on 24 Jul 2010
IA.  Analysis of Solar Active Regions and Activity from  23/2100Z
to 24/2100Z:  Solar activity was very low. Isolated low-level B-class
flares were detected. Region 1089 (S23E06) continued to gradually
decay and simplify. New Region 1090 (N23E58), a single-spot A-type
group, was numbered late in the period.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low. However, there is a chance for an isolated C-class flare from
Region 1089.
IIA.  Geophysical Activity Summary 23/2100Z to 24/2100Z:
Geomagnetic field activity was at quiet to (briefly) unsettled
levels.
IIB.  Geophysical Activity Forecast:  Geomagnetic field activity is
expected to be at mostly quiet levels during days 1 - 2 (25 - 26
July). Activity is forecast to increase to unsettled to active
levels on day 3 (27 July) due to the expected arrival of a recurrent
coronal hole high-speed wind stream.
