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 318 Issued at 2200Z on 14 Nov 2007IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z Solar activity was very low. No flares were detected.
The visible disk was spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 13-2100Z to 14-2100Z
The geomagnetic field was quiet to unsettled. ACE solar wind
measurements indicated Earth remained under the influence of a
recurrent coronal hole high-speed stream.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet to unsettled levels during 15 - 16 November
as the coronal hole high-speed stream gradually subsides. Field
activity is expected to decrease to quiet levels on 17 November.
