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 091 Issued at 2200Z on 01 Apr 2006IA. Analysis of Solar Active Regions and Activity from 31-2100Z to 01-2100Z Solar activity was very low. Today's activity consisted
of a few B-class flares. The largest of these was a B7 at 0040Z from
Region 865 (S12E07). This region continues to grow slowly,
particularly in the intermediate spots, and it does show some
magnetic complexity.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low. There is a chance for an isolated C-class event from
Region 865 during the next three days (02-04 April).
IIA. Geophysical Activity Summary 31-2100Z to 01-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled for the next three days (02-04
April)
