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.

IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z

Solar activity was low. Region 960 (S07W03) produced a few small C-class events as it continued to slowly decay and simplify. Region 959 (S11W31) reemerged during the period, from a spotless plage to a simple bipole with nine spots. Region 958 (S12W54) was quiet.
IB. Solar Activity Forecast
Solar activity is expected be low.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field was quiet. The GOES greater than 2 MeV electron flux attained high levels once again.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet throughout the forecast period.
