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 311 Issued at 2200Z on 07 Nov 2009IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z Solar activity was very low. Region 1030 (N25W25)
decayed into a spotless plage region today. No flares were observed
during the past 24 hours.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled, with a slight chance for an
active period at high latitudes, on day one (08 November). The
increase in activity is due to a weak recurrent coronal hole
high-speed stream. Quiet levels are expected on days two and three
(09-10 November).
