Propagation Summary
Solar activity was mostly very low throughout August.
This was only very minor flare activity occurring on 14-19 August with little significant affect.

The solar flux was mainly at normal levels, except on 16-17 August where moderate levels were observed.  On 18-19 August, levels were high. 

Geomagnetic field ranged from quiet to active.  Solar winds was at normal levels with the exception of  15-19 August due to a Coronal Hole High speed stream (CH HSS) moving towards an effective position, but levels returned to normal buy 19 August when conditions were quiet.

Propagation Forecast until 15 September
Solar activity is expected to continue at very low levels. The Solar flux is expected to reach high levels 13-15 Sep due to CH HSS influence.

Geomagnetic field activity is expected to be unsettled to active levels on 03-04 Sep, 07 Sep, and 11-15 Sep with a chance for G1 (Minor) geomagnetic storm levels on 20-21 Aug, again due to recurrent CH HSS activity.

The Parker Solar Probe
On 11 August, the Parker Solar Probe was launched.   The project is to study how Solar winds occur and to achieve more accurate prediction of their affect on the earth’s Ionosphere and terrestrial weather etc. More information can be found at:
