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 2002

IA. Analysis of Solar Active Regions and Activity from 10-2100Z to 11-2100Z

Solar activity was at moderate levels. A long duration M2 flare occurred at 10/2325 UTC just beyond the east limb (S20). A fast impressive non earth directed CME was associated with this event. Region 9866 (S08E47) continued to grow, although now at a gradual rate, and has developed a beta-gamma-delta magnetic configuration. Other activity consisted of two minor C-class flares. Four new Regions were numbered today: Region 9867 (S29E16), Region 9868 (N19E32), Region 9869 (N24E42) and Region 9870 (S17E62).
IB. Solar Activity Forecast
Solar activity is expected to be low to moderate. Region 9866 has the potential for M-class and major events.
IIA. Geophysical Activity Summary 10-2100Z to 11-2100Z
The geomagnetic field was at quiet to unsettled levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels. There is a slight chance of isolated active conditions.
