Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 213 Issued at 2200Z on 01 Aug 2009
IA.  Analysis of Solar Active Regions and Activity from  31/2100Z
to 01/2100Z:  Solar activity was very low. A very weak A-level event
was seen in GOES x-rays around 0243Z which was associated with
brightening in a spotless plage region near S26E06. The solar disk
was otherwise void of activity and continues to be without sunspots.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 31/2100Z to 01/2100Z:
The geomagnetic field was quiet during the past 24 hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for the next three days (2-4 August).
