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 155 Issued at 2200Z on 04 Jun 2006IA. Analysis of Solar Active Regions and Activity from 03-2100Z to 04-2100Z Solar activity continues at very low levels. B-class
flares were observed from newly numbered Region 892 (S08E67). This
new region rotated into view today as a small, but moderately
complex sunspot cluster.
IB. Solar Activity Forecast
Solar activity is expected to continue
at very low levels. There is a slight chance of a C-class flare from
Region 892.
IIA. Geophysical Activity Summary 03-2100Z to 04-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to range from quiet to minor storming. Quiet to unsettled
conditions are expected on 05 and 06 May. A large recurrent coronal
hole is expected to rotate into a geoeffective position on 07 May
and produce active to minor storm periods.
