Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 286 Issued at 2200Z on 13 Oct 2010
IA. 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.
