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 2006IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z Solar activity has been low with two C-class flares
from Region 898 (S06W55). Region 899 (S05E40) was quiet and stable.
IB. Solar Activity Forecast
Solar activity is expected to be low,
although there is a slight chance of an isolated M-class flare.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field was quiet. The solar wind speed remains
elevated due to a coronal hole high speed stream but has steadily
declined during the past 24 hours. Enhancement of 10 MeV protons
continues but has been steadily declining. The greater than 2 MeV
electron flux reached high levels during the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for July 8, then active on July 9 with a
chance for minor storm periods due to the arrival of the flank of
the July 6 CME. Unsettled to active conditions due to persistence
are expected for July 10.
