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 319 Issued at 2200Z on 15 Nov 2007IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z Solar activity was very low. The visible disk remained
spotless. A CME departed the southwest limb late on 14 November, but
was not Earth-directed.
IB. Solar Activity Forecast
Solar activity is expected to remain
very low.
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
The geomagnetic field was quiet to unsettled with periods of active
to minor storm levels detected at high latitudes. 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 mostly quiet levels during the period.
