It rose to three again on Thursday the 13th due to an enhanced solar wind stream. The solar flux index remained around 70 thanks to a total lack of sunspots. It is hard to …

Propagation News – 9 June 2019

We had a very quiet, settled Sun last week. The solar flux index never got above 70, reflecting a complete lack of sunspots, while the Kp index eventually decreased to one or two, due to a lack of coronal holes on the solar surface. The net result was that HF conditions were not bad, but definitely not outstanding. Last weekend’s …
