Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 244 Issued at 2200Z on 01 Sep 2009
IA. Analysis of Solar Active Regions and Activity from 31/2100Z
to 01/2100Z: Solar activity was very low. Region 1025 (N17E18) a
small, simple Bxo continues to grow. No flares were observed.
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.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet on day 1 (2 September) and quiet to unsettled
on days 2 and 3 (3 -4 September). The activity is due to a recurrent
coronal hole high speed stream.
