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 282 Issued at 2200Z on 09 Oct 2005

IA. Analysis of Solar Active Regions and Activity from 08-2100Z to 09-2100Z

Solar activity was at very low levels. Region 813 (S08W35) continues to show steady decay in sunspot area. Region 813 remains a magnetic beta spot group. No new regions were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be at very low levels.
IIA. Geophysical Activity Summary 08-2100Z to 09-2100Z
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. The coronal hole high speed stream has begun to wane but may yet produce further periods of active conditions through 10 October.
