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 188 Issued at 2200Z on 07 Jul 2009IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z Solar activity was very low. No x-ray flares were
observed during the past 24 hours. Region 1024 (S27W39) continued
to decay and activity from the region was significantly reduced.
The remainder of the disk was quiet and stable.
IB. Solar Activity Forecast
Solar activity is expected to remain
very low with a slight chance for an isolated C-flare from Region
1024.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field was quiet during the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet on day one (8 July). An increase to quiet to
unsettled is expected for day two (9 July) due to possible coronal
hole effects. Conditions should be predominately quiet for day
three (10 July).
