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 316 Issued at 2200Z on 12 Nov 2006

IA. Analysis of Solar Active Regions and Activity from 11-2100Z to 12-2100Z

Solar activity was low. Region 923 (S04E21) produced three C-class flares over the past 24 hours, the largest of which was a C1.1 at 12/1046Z.
IB. Solar Activity Forecast
Solar activity is expected to be very low to low. Region 923 may produce further C-class activity.
IIA. Geophysical Activity Summary 11-2100Z to 12-2100Z
The geomagnetic field was quiet to unsettled. Solar wind speed has decreased steadily to about 500 km/s. The greater then 2 MeV electron flux at geosynchronous orbit reached high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled for the next three days (13 - 15 November).
