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 250 Issued at 2200Z on 07 Sep 2006IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z Solar activity was very low. Region 909 (S09E09)
produced a long duration B4.2 flare at 07/0746 UTC. No new regions
were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be very
low with a slight chance for an isolated C-flare.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field was quiet with an isolated active period at
middle latitudes between 07/0600 - 0900 UTC. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels again
today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly quiet.
