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 256 Issued at 2200Z on 13 Sep 2010

IA. Analysis of Solar Active Regions and Activity from 12-2100Z to 13-2100Z

Solar activity was very low. The disk was quiet and stable.
IB. Solar Activity Forecast
Solar activity is expected to remain at very low levels. A slight chance for C-class activity is possible from Region 1106 (S19E44) for the next three days (14 - 16 September).
IIA. Geophysical Activity Summary 12-2100Z to 13-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet levels for days one and two (14 - 15 September). Quiet to unsettled conditions, with isolated high latitude active periods, are possible on day three (16 September) due to the combined effects from the 11 September CME and a weak coronal hole high speed stream.
