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 280 Issued at 2200Z on 07 Oct 2005

IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z

Solar activity was at very low levels. Region 813 (S08W08) continues to show slow decay in sunspot coverage. The magnetic gamma structure in Region 813 is weak, but remains intact. No new regions were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be at very low to low levels. Region 813 remains capable of producing an isolated C-class flare.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field was at quiet to unsettled levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on 08 October. Mostly active to isolated minor storm conditions may be possible on 09 and 10 October due to a recurrent high speed coronal hole stream.
