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 329 Issued at 2200Z on 24 Nov 2008IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z Solar activity was very low. The visible solar disk
remained spotless.
IB. Solar Activity Forecast
Solar activity is expected to remain
very low.
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be unsettled to occasionally active as a recurrent
coronal hole high speed stream becomes geoeffecttive. There is a
slight chance for isolated minor storm activity at high latitudes.
These conditions are expected to persist throughout the forecast
period.
