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 316 Issued at 2200Z on 11 Nov 2008IA. Analysis of Solar Active Regions and Activity from 10-2100Z to 11-2100Z Solar activity was very low during the past 24 hours.
The GOES soft x-ray flux remained below the B1 level throughout the
period. Region 1008 (N33W08) showed slow growth accompanied by
occasional plage fluctuations in H-alpha during the past 24 hours,
but was otherwise quiet and stable.
IB. Solar Activity Forecast
Solar activity is generally expected
to be very low for the next three days (12-14 November). However
there is a slight chance for an isolated C-class event from Region
1008.
IIA. Geophysical Activity Summary 10-2100Z to 11-2100Z
The geomagnetic field was quiet during the past 24 hours. The greater
than 2 MeV electron flux at geosynchronous orbit reached high
levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for the next three days (12-14 November).
