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 222 Issued at 2200Z on 10 Aug 2010IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z Solar activity was very low. Three B-class flares were
observed during the period, including a long-duration B8 flare at
10/1701Z from new Region 1097 (N33E71). Region 1096 (N21W33) showed
an increase in spot count as well as areal coverage, and was
classified as a Cri 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 1096.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
Geomagnetic field activity was at quiet to unsettled levels. The
greater than 2 MeV electron flux at geosynchronous orbit reached
high levels today.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is
expected to be quiet to unsettled, with an isolated active period
possible, on day one (11 August) due to effects of the full-halo CME
observed on 07 August. Quiet levels are expected on days two and
three (12-13 August.)
