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 281 Issued at 2200Z on 08 Oct 2010IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z Solar activity was very low. A few B-class events were
observed originating on the east limb near S24 in the vicinity of
old returning Region 1106 (S22, L-217).
IB. Solar Activity Forecast
Solar activity is expected to remain
at very low levels for the next three days (09 - 11 October).
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic field was at mostly quiet levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly quiet for days one and two (09 - 10 October).
By day three (11 October), geomagnetic activity is expected to
increase to quiet to unsettled levels, with isolated active periods
at high latitudes. The forecasted increase in activity is due to a
geoeffective coronal hole high speed stream coupled with a possible
glancing blow from the 06 October full-halo CME.
