August 2016

Propagation Summary

Solar activity was at very low levels from 11-14 July with only a few simple sunspot regions.  

A sunspot group emerged on 15-17 July producing 13 C Class flares, the largest of which was late on the 17 July.

The Solar Flux reached high levels throughout the period, particularly on 17 July at 1630.

Geomagnetic field activity ranged from quiet to G1 (Minor) storm levels. The majority of the period was under the influence of high speed solar wind streams from a large coronal hole peaking on 12 July causing minor storm levels. The rest of the period was at quiet to unsettled levels with quiet conditions observed on 17 July.

Propagation Forecast up to 13 August

Low levels of solar activity are expected, with a chance of M-Class flares from 5-13 August.

The solar Flux is forecast at high levels from 5-13 August due to Coronal Hole High Speed Stream activity.  Normal to moderate levels are expected for the remaining forecast period.

Geomagnetic field activity is expected to be at G1 minor storm levels 3-4 and 8 august, causing

unsettled to active levels. 

HF propagation is likely to be affected mostly on 3, 4 and 8 August with the possibility of radio black outs. http://bit.ly/dxlatest
