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 074 Issued at 2200Z on 14 Mar 2004IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z Solar activity was very low. Region 570 (S13W32)
produced occasional B-class activity including a B3 flare with an
associated 130 sfu Tenflare at 14/2035Z. This region continues to
slowly decay and the delta configuration that persisted for the past
several days is no longer evident. No other significant activity or
changes were observed.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low. C-class activity is possible from Region 570.
IIA. Geophysical Activity Summary 13-2100Z to 14-2100Z
The geomagnetic field was quiet to active. Slightly elevated solar
wind speed with periods of sustained southward Bz produced the
disturbed conditions. 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 with isolated active periods.
