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 082 Issued at 2200Z on 22 Mar 2004IA. Analysis of Solar Active Regions and Activity from 21-2100Z to 22-2100Z
Solar activity was at low levels. Region 574 (S03W13)
produced a C8/Sf flare at 22/0616Z. This region continues to decay
and has simplified in magnetic complexity to a beta configuration.
Region 578 (N16E20) shows signs of decreasing area and produced a
number of B-class and minor C-class flares today. New Region 579
(S11E48) was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be at
low levels. Regions 574 and 578 have the potential for C-class
flares.
IIA. Geophysical Activity Summary 21-2100Z to 22-2100Z
The geomagnetic field was at quiet to unsettled levels. The greater
than 2 MeV electron flux at geosynchronous orbit reached high levels
today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet to unsettled levels.
