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 302 Issued at 2200Z on 29 Oct 2006IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 29-2100Z Solar activity was very low.
IB. Solar Activity Forecast
Solar activity is expected to continue
at very low levels.
IIA. Geophysical Activity Summary 28-2100Z to 29-2100Z
The geomagnetic field was quiet to active. Activity was due to the
continued influence of a geoeffective coronal hole high speed
stream. Solar wind speed at ACE is currently elevated around 540
km/s.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled with isolated active periods
possible at high latitudes on 30 October. On 31 October and 01
November, quiet to unsettled conditions are expected.
