Propagation News – 16 August 2015

Long-range HF propagation showed signs of picking up this week. Whether this was due to the slow change to better autumnal propagation, or from having a short period of fairly settled geomagnetic conditions, is debatable. The settled conditions didn’t last long though as the Kp index was up to four on Thursday due to plasma from a high-speed solar wind …

Propagation News

HF propagation conditions during last weekend’s IOTA contest were pretty dire. This was due to a perfect storm of typical summer conditions, a fairly low sunspot count and poor geomagnetic conditions, reflected in a Kp index of three. This was due to the arrival of material from a coronal mass ejection and the onset of a weak high speed solar …
