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 198 Issued at 2200Z on 17 Jul 2006IA. Analysis of Solar Active Regions and Activity from 16-2100Z to 17-2100Z Solar activity was very low. Region 900 (S05E02)
remains a beta magnetic configuration. Several enhancements and
near surging have been observed in this region which have resulted
in slight fluctuations in the x-ray background. No new regions were
numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be very
low. There is a slight chance for an isolated C-class flare from
Region 900.
IIA. Geophysical Activity Summary 16-2100Z to 17-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be predominately quiet.
