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 240 Issued at 2200Z on 28 Aug 2010IA. Analysis of Solar Active Regions and Activity from 27-2100Z to 28-2100Z Solar activity was very low. Region 1101 (N12E21)
produced a few B-class flares during the past 24 hours.
IB. Solar Activity Forecast
Solar activity is forecast to be very
low for the next 3 days (29-31 August).
IIA. Geophysical Activity Summary 27-2100Z to 28-2100Z
The geomagnetic field was mostly quiet to unsettled with an isolated
period of active conditions between 27/21-28/00Z. The greater than 2
MeV electron flux at geosynchronous orbit was at high levels
throughout the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
forecast to be mostly quiet to unsettled for the next 3 days (29-31
August).
