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 235 Issued at 2200Z on 23 Aug 2006IA. Analysis of Solar Active Regions and Activity from 22-2100Z to 23-2100Z Solar activity was very low. Region 905 (S08E47), the
only sunspot group on the visible disk, produced isolated B-class
flares. This active region exhibited little change this period and
maintains a reversed polarity magnetic structure.
IB. Solar Activity Forecast
Solar activity is expected to continue
at very low levels. There is a slight chance for a C-class flare
from Region 905.
IIA. Geophysical Activity Summary 22-2100Z to 23-2100Z
The geomagnetic field was quiet to unsettled. Solar wind speed
declined from a maximum of near 500 km/s to end the period at 420
km/s. 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 quiet to unsettled with isolated active periods.
