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. rsgb.org/propquest 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 […]
