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 248 Issued at 2200Z on 05 Sep 2006IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z Solar activity was very low. New Regions 907 (S13E44)
and 908 (S13E71) were numbered today. New Region 908 is likely the
return of old Region 904 (S14,L=121).
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic field was quiet to unsettled. Solar wind speed is
still elevated at approximately 500 km/s but has been in decline
this period. The greater than 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.
