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 328 Issued at 2200Z on 23 Nov 2008IA. Analysis of Solar Active Regions and Activity from 22-2100Z to 23-2100Z
Solar activity was very low.
IB. Solar Activity Forecast
Solar activity is expected to remain
very low.
IIA. Geophysical Activity Summary 22-2100Z to 23-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet on day one (24 November), On days two and
three (25-26 November), the geomagnetic field is expected to become
unsettled to active, with a slight chance of isolated minor storm
conditions at high latitudes, under the influence of a recurrent
coronal hole high speed stream.
