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 314 Issued at 2200Z on 10 Nov 2007IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z Solar activity was very low. The visible disk remained
spotless and no flares were observed.
IB. Solar Activity Forecast
Solar activity is expected to remain
very low
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly quiet on days 1 and 2 of the forecast period
(11-12 November). Activity is expected to increase to unsettled to
occasionally active levels at mid lititudes on day 3 (13 November),
with a slight chance for minor storming at high latitudes, as a
recurrent coronal hole becomes geoeffective.
