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 238 Issued at 2200Z on 25 Aug 2008IA. Analysis of Solar Active Regions and Activity from 24-2100Z to 25-2100Z
Solar activity was at very low levels. The visible
disk remained spotless.
IB. Solar Activity Forecast
Solar activity is expected to remain
at very low levels.
IIA. Geophysical Activity Summary 24-2100Z to 25-2100Z
The geomagnetic field was quiet. 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 during the forecast period (26 - 28 August).
