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 277 Issued at 2200Z on 04 Oct 2006IA. Analysis of Solar Active Regions and Activity from 03-2100Z to 04-2100Z Solar activity was very low. A CME was first observed
off the west limb on LASCO imagery at 04/0854 UTC. This CME probably
originated from active Region 915 (S06, L=291) which rotated around
the west limb on 03 October. The ejecta was directed to the west and
is not expected to be geoeffective.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 03-2100Z to 04-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels again today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly quiet.
