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 005 Issued at 2200Z on 05 Jan 2006

IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z

Solar activity was low. Region 843 (N12W64) produced an impulsive C4/Sf flare at 0923 UTC. There was a Type II sweep (estimated shock speed approx. 1100 km/s) associated with the flare. This event followed soon after a long duration B8 x-ray flare from nearby Region 841 (N13W91) which attained maximum at 0742 UTC. The activity was preceded by plage brightenings in both regions.
IB. Solar Activity Forecast
Solar activity is expected to be very low to low. Region 843 could produce an isolated C-class flare.
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit was high.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled. A high speed solar wind stream may boost activity slightly during the last two days of the period.
