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 207 Issued at 2200Z on 25 Jul 2008IA. Analysis of Solar Active Regions and Activity from 24-2100Z to 25-2100Z
Solar activity was very low. No flares were observed.
The visible disk was spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 24-2100Z to 25-2100Z
Geomagnetic field activity was at mostly quiet levels. The greater
than 2 MeV electron flux at geosynchronous orbit reached high levels
during the period.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is
expected to be at quiet levels through the period (26 - 28 July).
