Propagation News

RSGBOctober 9, 2015  The sun severely disrupted the HF bands again this week. A high-speed solar wind stream with a south-facing Bz magnetic component continued to interact strongly with the Earth’s geomagnetic field. Strong, G3 level geomagnetic storming was observed at high latitudes and the K index hit seven on Wednesday evening. There were long periods on Wednesday and Thursday …

Propagation News – 20 September 2015

RSGB September 18, 2015 Despite ongoing solar coronal holes, and their contribution to the high-speed solar wind, HF conditions have fared a little better than in previous weeks. This is due to the traditionally better autumnal HF conditions, which should improve further as the month goes on. Despite the geomagnetic K-index never really dropping below three, and often hitting five, …
