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 125 Issued at 2200Z on 05 May 2006IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z Solar activity decreased to very low levels. Regions
875 (S13W85) and 880 (S08E50) were limited to minor B-class flare
activity. Region 881 (S12E75) was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be at
very low to low levels.
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic field ranged from quiet to minor storm levels. The
elevated conditions were due to a co-rotating interaction region.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to range from quiet to minor storm levels, possibly
isolated severe storm conditions on 06 May due to a recurrent high
speed coronal hole stream. Predominantly unsettled to active
conditions are expected on 07 and 08 May due to continued coronal
hole effects.
