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 08-2100Z to 09-2100Z

Solar activity was very low.
IB. Solar Activity Forecast
Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 08-2100Z to 09-2100Z
The geomagnetic field was at quiet to unsettled levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels for 10 July. Unsettled to active conditions, with isolated minor storm periods, are expected for 11-12 July. An increase in activity is expected due to a recurrent coronal hole high speed stream.
