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 315 Issued at 2200Z on 11 Nov 2007IA. Analysis of Solar Active Regions and Activity from 10-2100Z to 11-2100Z Solar activity was very low. The visible disk remained
spotless.
IB. Solar Activity Forecast
Solar activity is expected to remain
very low.
IIA. Geophysical Activity Summary 10-2100Z to 11-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to begin the period at quiet levels. The arrival of a
coronal hole high speed stream during the latter part of 13 November
should raise levels to unsettled, with an occasional active period.
Isolated minor storm periods are possible at high latitudes. The
elevated activity is expected to persist through 14 November.
