Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 305 Issued at 2200Z on 01 Nov 2010
IA. Analysis of Solar Active Regions and Activity from 31/2100Z
to 01/2100Z: Solar activity was low. A C1 flare was observed at
01/0443Z from Region 1117 (N22, L=063) as it rotated around the west
limb. Region 1120 (N39E41) has been quiet.
IB. Solar Activity Forecast: Solar activity is expected to be very
low to low on day one (02 November). Very low conditions are
expected on days two and three (03 – 04 November) as Region 1117
rotates off the solar disk.
IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z:
The geomagnetic field was at quiet levels.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at quiet to unsettled levels, with a slight chance
for active conditions during the next three days (02 – 04 November).
The increase in activity is due to a recurrent coronal hole
high-speed stream.
