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 083 Issued at 2200Z on 24 Mar 2006IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z Solar activity was very low. New Region 864 (S05W61)
was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be very
low with a slight chance for an isolated C-flare.
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels again today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled with the possibility of isolated
active periods on 25 and 26 March. On 27 March, mostly quiet
conditions are expected.
