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 276 Issued at 2200Z on 03 Oct 2005IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z Solar activity levels were very low again this period.
Old active Region 808 is rotating on the southeast limb near S10.
This was a very active region during its last passage across the
visible disk; however, there has been no significant eruptive
activity observed over the past few days.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low. C-class activity is possible from old Region 808 as it
rotates into view on 04 October. There is also a slight chance for
an M-class flare.
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic field was quiet to unsettled. The greater than 2 MeV
electrons at geosynchronous orbit were at high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to continue at quiet to unsettled levels with isolated
active periods.
