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.

SDF Number 317 Issued at 2200Z on 13 Nov 2005

IA. 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.
