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 220 Issued at 2200Z on 08 Aug 2010IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z Solar activity was very low. Only B-class flares were
observed during the past 24 hours.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low with C-class flares likely from Regions 1093 (N10E15) and
1095 (S17E08). A chance of M-class activity is possible from Region
1093.
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
Geomagnetic field activity was quiet. The greater than 2 MeV electron
flux at geosynchronous orbit was at high levels again today.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is
expected to be mostly quiet with a chance of isolated unsettled
levels for the next three days (09 - 11 August).
