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 142 Issued at 2200Z on 22 May 2006IA. Analysis of Solar Active Regions and Activity from 21-2100Z to 22-2100Z Solar activity was very low. Today's activity consisted
of a single, B6 x-ray event at 1952Z from Region 884 (S13E08). The
event was accompanied by a slow Type II radio sweep (estimated
velocity 548 km/s). Region 884 and Region 885 (S12E17) are the only
spotted regions on the disk and are stable and quiet.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low during the next three days (23-25 May).
IIA. Geophysical Activity Summary 21-2100Z to 22-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for the next two days (23-24 May). Generally
unsettled conditions are expected on the third day (25 May) due to
recurrence.
