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 2007IA. Analysis of Solar Active Regions and Activity from 25-2100Z to 26-2100Z Solar activity was at very low levels. Region 975
(N03W38) decayed to an AXX spot group.
IB. Solar Activity Forecast
Solar activity is expected to remain
at very low levels.
IIA. Geophysical Activity Summary 25-2100Z to 26-2100Z
The geomagnetic field was at quiet to unsettled levels, due to the
continued influence of a coronal hole high speed stream. The
greater than 2 MeV electron flux at geosynchronous orbit reached
high levels again today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at mostly quiet levels for the forecast period (27 to
29 November).
