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 286 Issued at 2200Z on 13 Oct 2010IA. Analysis of Solar Active Regions and Activity from 12-2100Z to 13-2100Z Solar activity was very low. Region 1112 (S17E14)
remained stable and quiet. New Region 1113 (N17E76) produced several
B-class x-ray events, the largest a B4 event at 13/1627Z.
IB. Solar Activity Forecast
Solar activity is expected to be very
low for the next 3 days (14-16 October).
IIA. Geophysical Activity Summary 12-2100Z to 13-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron Flux
at geosynchronous orbit reached high levels during the period.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for days 1 and 2 (14-15 October) and quiet to
unsettled with a chance for isolated periods of active conditions on
day 3 (16 October). The increased activity is expected due to the
possible arrival of a CME observed on 11 October.
