The solar minimum continued last week with zero sunspots being recorded. The good news was that geomagnetic conditions were quite settled with a maximum Kp index of three recorded. Most of the week it was between zero and two, which meant that the HF bands were performing to seasonal averages. shows that maximum usable […]

We had a mixed bag of HF propagation over the last seven days, although Monday saw maximum usable frequencies over a 3,000km path climb above 21MHz. Conditions were less good on Thursday morning, mainly due to an elevated Kp index, which reached four thanks to an enhanced solar wind with a south-facing Bz component. There […]

We had a real mixed bag in terms of HF propagation last week. The middle of the week through to Friday was actually quite good. Peter, G3XJE ran a very comprised 20m WSPR station from the Propagation Studies Committee stand at the National Hamfest and was picked up as far afield as the southern states […]

Last week continued with zero sunspots, making it now more than 190 days this year that the solar surface has remained spotless. Many solar scientists predict that 2019 will have a total of more than 250 days without sunspots, which would make it the ninth most ‘spotless’ year since records began in 1849. Current research […]

We had a relatively settled week, with the Kp index remaining at or below four. The high-speed solar wind was the reason for the K-index increase, but it didn’t significantly degrade HF propagation. We are seeing a change to more autumnal HF conditions with north to south paths opening up quite regularly. The summer doldrums […]

It was a quiet week, geomagnetically speaking, with the Kp index generally not rising above two. But a lack of sunspots didn’t help HF propagation, which was decidedly uninspiring. There were some highlights though, mostly on FT8. Columbia was decoded on Wednesday evening on 15 metres at a time when CW and SSB users might […]
