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 274 Issued at 2200Z on 01 Oct 2006IA. Analysis of Solar Active Regions and Activity from 30-2100Z to 01-2100Z Solar activity was very low.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 30-2100Z to 01-2100Z
The geomagnetic field was at quiet to minor storm conditions.
Activity was due to the continued influence of a coronal hole high
speed stream. The greater than 2 MeV electron flux at geosynchronous
orbit reached high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled.
