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 312 Issued at 2200Z on 08 Nov 2009IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z Solar activity was very low. No flares were observed.
The visible disk was spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic field was at quiet to unsettled levels, due to a weak
recurrent coronal high-speed stream. Wind speeds increased from 260
km/s to 451 km/s at 08/1934Z. The interplanetary magnetic field
(IMF) showed an enhancement of total field of 11 nT, while the
southward component reached -9 nT.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet, with a chance for an isolated unsettled period
early in the period, on day one (09 November). Quiet levels are
expected for days two and three (09-11 November).
