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 092 Issued at 2200Z on 02 Apr 2006IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z Solar activity was very low. Region 865 (S11W06)
continues to show an increase in area and remains a beta gamma delta
magnetic configuration. New Region 867 (S16E16) was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low. Isolated C-class flares are possible from Regions 865
and 867.
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled on 03 and 04 April. On 05 April,
mostly quiet to unsettled conditions are expected with isolated
active periods possible as a coronal hole high speed stream becomes
geoeffective.
