Last weekend’s IARU contest saw a lot of action on the HF bands, which just goes to show that it isn’t all about sunspots. In fact, we have now gone more than three weeks without sunspots, which has been described as almost a decade-class event. The last time the sun lost its spots for 21 […]

Summer Sporadic-E brought some unusual short-skip propagation to 20 metres this week, with contacts being enabled between parts of the UK. Signals between Southern England and Scotland were very loud mid-morning after Sporadic-E cloud settled over the British Isles on Monday.

However, by Wednesday the ionosphere had calmed down and the index returned to a more settled Kp=1. Much of the […]

It was more of the same last week with virtually zero sunspots, but some sporadic E to keep us amused on HF. We say virtually zero sunspots as a group had just appeared over the sun’s limb, pushing the sunspot number to 16 as the time of writing. This represents 10 for the single group […]
