Propagation News – 3 November 2024
Last weekend’s CQWW SSB contest showed just how good autumnal HF conditions can be. Many contesters worked more than 100 countries or DX entities on each and every HF band. With a solar flux index of 238 on Saturday and 246 on Sunday, plus low Kp indices all weekend, it was about as good as […]

Last week’s solar conditions couldn’t have been much better. We had a week of high solar flux indices, relatively calm geomagnetic conditions and, other than an X-class solar flare, not much else to report. The solar flare originated from active region 3869 and reached a strong X3.3 in the early hours of 24 October. This […]
Propagation News – 20 October 2024
The past week has been characterised by a low geomagnetic Kp index and excellent conditions on HF, including the 10m band. With a solar flux index between 168 and 195, and a Kp index that never rose above four, conditions have been better than the previous week, which suffered from the bad effects of solar […]

What a difference a week makes when it comes to HF propagation! This last week has been characterised by solar flares, coronal mass ejections (CMEs), and an elevated Kp index. Put together, this has resulted in dire conditions on HF, reminiscent of a solar minimum. A visible aurora was seen from the UK once again […]
Propagation News – 6 October 2024
In the first week of October, the 10m band began to show what it is capable of. With a solar flux index in the high 200s and calm geomagnetic conditions, DX was plentiful. Nick, VK9DX on Norfolk Island was audible on SSB all morning on Wednesday 2 October and only wanted to work G stations. […]
Propagation News – 29 September 2024
Solar activity is back to moderate levels with an M3.7 solar flare detected on 22 September. Newly assigned AR 3835 in the south-east quadrant is the main source, and the event looks to have thrown a stream of plasma into space. The latest model suggested a possible passage near our planet by the 25th and […]
