Solar activity report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 330 Issued at 2200Z on 26 Nov 2010IA. 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).
