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 317 Issued at 2200Z on 13 Nov 2005IA. Analysis of Solar Active Regions and Activity from 12-2100Z to 13-2100Z Solar activity was moderate. Region 822 (S06E66)
produced an M2.5 flare at 13/1451 UTC, and several C-class events in
the last 24 hours. This group is the only spotted region on the
solar disk and is still to close to the limb for a detailed
analysis.
IB. Solar Activity Forecast
Solar activity is expected to be low.
Region 822 has the potential to produce an isolated M-class flare.
IIA. Geophysical Activity Summary 12-2100Z to 13-2100Z
The geomagnetic field was quiet to active. The solar wind averaged
around 420 km/s with the IMF Bz fluctuating between +1 to -4 nT.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled.
