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 253 Issued at 2200Z on 10 Sep 2006

IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z

Solar activity was very low. Region 909 (S11W30) produced a long duration B6 event at 10/0723 UTC.
IB. Solar Activity Forecast
Solar activity is expected to be very low with a slight chance for an isolated C-class event.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic field was quiet to unsettled. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled for 12-13 September due to possible effects from a coronal hole high speed stream. Quiet conditions are expected for 14 September.
