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 2005

IA. 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.
