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 159 Issued at 2200Z on 08 Jun 2007

IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z

Solar activity continued low. Region 960 (S08W17), the most prominent of the spotted regions visible, continues to simplify and decay. It has produced frequent small C-class activity through the interval. The other two spotted regions have been quiet.
IB. Solar Activity Forecast
Solar activity is expected to be low. Region 960 retains the potential for an isolated M-class flare.
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic field has been quiet. The GOES greater than 2 MeV electron flux was at high levels once again.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to persist at quiet conditions through the forecast period.
