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 283 Issued at 2200Z on 10 Oct 2005IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z Solar activity remains at very low levels. Region 813
(S07W48) continues to decay.
IB. Solar Activity Forecast
Solar activity continues at very low
levels.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic field was quiet to unsettled. A coronal hole high
speed stream remains in effect, with solar wind speed ranging 600 -
650 km/s. The greater than 2 MeV electron flux at geosynchronous
orbit was at high levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to continue at quiet to unsettled levels. Isolated active
periods are possible at high latitudes.
