Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 330 Issued at 2200Z on 26 Nov 2010
IA. Analysis of Solar Active Regions and Activity from 25/2100Z
to 26/2100Z: Solar activity has been very low. Region 1128 (S14E46)
has grown slightly in extent and is a Bxo-Beta type spot group.
IB. Solar Activity Forecast: Solar activity is expected to very
low, with a slight chance for an isolated C-class event from Region
1128.
IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field has been quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet for day one (27 November). Day two (28
November) is expected to be quiet with a slight chance for isolated
unsettled periods due to the CME observed on 24 November becoming
geo-effective. Conditions are expected to return to quiet levels on
day three (29 November).
