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 218 Issued at 2200Z on 05 Aug 2008IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z Solar activity was very low. No flares were observed
during the past 24 hours. The solar disk was spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet on day one (6 August), quiet to unsettled on
day two (7 August), and unsettled to active on day three (8 August).
The increase in activity is forecast due to a corotating interaction
region.
