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 203 Issued at 2200Z on 22 Jul 2006IA. Analysis of Solar Active Regions and Activity from 21-2100Z to 22-2100Z Solar activity was very low. New Region 901 (N06E70)
produced several B-class flares. Region 900 (S06W65) is currently
spotless.
IB. Solar Activity Forecast
Solar activity is expected to continue
at very low levels.
IIA. Geophysical Activity Summary 21-2100Z to 22-2100Z
The geomagnetic field was mostly quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet on 23 July. Quiet to active levels are
expected on 24-25 July, with possible minor storm conditions at high
latitudes. The elevated conditions are due to the arrival of a CME
from 20 July and a recurrent coronal hole moving into geoeffective
position.
