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 220 Issued at 2200Z on 08 Aug 2006IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z Solar activity was very low. New Region 903 (S09E56)
was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to remain
at very low levels.
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic field was quiet to active. Solar wind speed at ACE
remains elevated at around 600 km/s. 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 with isolated active periods
possible on 09 August. On 10 and 11 August, quiet to unsettled
conditions are expected.
