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 208 Issued at 2200Z on 26 Jul 2008IA. Analysis of Solar Active Regions and Activity from 25-2100Z to 26-2100Z Solar activity was very low. No flare activity was
observed. The visible disk remained spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 25-2100Z to 26-2100Z
Geomagnetic field activity was at quiet levels. The greater than 2
MeV electron flux at geosynchronous orbit was high.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is
expected to be at mostly quiet levels through the period (27 - 29
July).
