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 221 Issued at 2200Z on 09 Aug 2005IA. Analysis of Solar Active Regions and Activity from 08-2100Z to 09-2100Z Solar activity has been very low. The only activity
observed during the last 24 hours were low level B-class flares.
Region 792 (N10W82) and 794 (S13W48) are both indicating a decay
phase. No new sunspot regions were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be very
low with a chance for an isolated C-class flare.
IIA. Geophysical Activity Summary 08-2100Z to 09-2100Z
The geomagnetic field was at quiet to unsettled levels. The greater
than 2 MeV electron flux at geosynchronous orbit was at high levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet to unsettled levels.
