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 327 Issued at 2200Z on 23 Nov 2005IA. Analysis of Solar Active Regions and Activity from 22-2100Z to 23-2100Z Solar activity was at very low levels. Regions 822
(S07W63) and 824 (S14E32) have been quiescent. No new regions were
numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be at
very low to low levels.
IIA. Geophysical Activity Summary 22-2100Z to 23-2100Z
The geomagnetic field was at quiet to unsettled levels. A weak shock
was observed by ACE at approximately 22/2100 UTC. Following the
shock, the solar wind briefly reached a maximum speed of about 500
km/s and the IMF turned southward to about -5 nT.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet to unsettled levels.
