Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 311 Issued at 2200Z on 07 Nov 2010
IA. Analysis of Solar Active Regions and Activity from 06/2100Z
to 07/2100Z: Solar activity was at low levels. Region 1121 (S18E36)
produced a C5/1F at 07/0141Z. Region 1121 was classified as an Esi
spot group, with a Beta-Gamma magnetic configuration. No new regions
were numbered. A small, faint earth-directed CME was observed on
both STEREO A and B coronagraph imagery, beginning at 07/0410Z.
IB. Solar Activity Forecast: Solar activity is expected to be at
low to moderate levels, with a chance for high levels.
IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z:
The geomagnetic field was at quiet levels.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at quiet to unsettled levels, with isolated active
levels at high latitudes, on days one and two (08-09 November).
Quiet levels are expected on day three (10 November). Further
analysis will be required to determine if the CME observed earlier
will be geoeffective. There is a slight chance for a greater than 10
MeV proton event from Region 1121.
