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 287 Issued at 2200Z on 14 Oct 2011IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z Solar activity was low. Despite 9 regions on the disk,
only low level C-class flares have occurred.
IB. Solar Activity Forecast
Solar activity is expected to be low
for the next 3 days (15-17 October).
IIA. Geophysical Activity Summary 13-2100Z to 14-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be unsettled to active with an isolated minor storm
possible on day 1 (15 October) and mostly unsettled with
intermittent active periods on days 2-3 (16-17 October). The
