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 223 Issued at 2200Z on 11 Aug 2010IA. Analysis of Solar Active Regions and Activity from 10-2100Z to 11-2100Z Solar activity was very low. Several low-level B-class
flares were observed during the period. Region 1098 (N15E28) was
numbered and was classified as a Dro spot group with a beta magnetic
configuration.
IB. Solar Activity Forecast
Solar activity is expected to be very
low, with a chance for a C-class flare from Region 1098.
IIA. Geophysical Activity Summary 10-2100Z to 11-2100Z
The geomagnetic field was at quiet to unsettled levels, with a single
unsettled period between 11/06-09Z. The greater than 2 MeV electron
flux at geosynchronous orbit was at high levels today.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is
expected to be quiet for the next three days (12-14 August).
