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 070 Issued at 2200Z on 11 Mar 2006IA. Analysis of Solar Active Regions and Activity from 10-2100Z to 11-2100Z Solar activity was very low. Region 856 (S09W89)
produced a long-duration B-class flare at 11/1400Z. No evidence of
an associated CME was observed; however, LASCO imagery was not
available at the time of issue.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 10-2100Z to 11-2100Z
The geomagnetic field was quiet to active. Active conditions
followed the onset of a coronal hole high speed stream.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled with a chance for isolated active
periods on 12 March. Quiet to unsettled conditions are expected for
13-14 March.
