Well, no one predicted last week’s geomagnetic disturbance. In case you missed it, the Kp index rose to four on Monday the 11th January. This was caused by the arrival of an interplanetary shock wave from a coronal mass ejection on the Sun, which occurred on Thursday the 7th. NOAA had been predicting a settled […]

We start by welcoming in 2021, and here’s hoping that it proves to be more fruitful than 2020 in terms of HF propagation. We’ve started the New Year with zero sunspots and a solar flux index back in the mid-70s on Thursday the 7th. The STEREO Ahead spacecraft is not showing anything of note around […]

HF conditions were not terribly good over the last week with maximum usable frequencies down in general. The best DX has been on 40m, especially around greyline times, although there has been a little winter Sporadic-E activity on 10 metres as well that has seen Italy and Spain appearing on FT8, as well as Brazil […]

We’ve had another week of lacklustre sunspot activity. The solar flux index has been pegged at around 82, caused by the two tiny sunspots in active region 2793. Having said that, a lack of coronal hole activity has meant that geomagnetic conditions have been settled, with a maximum Kp index of two, but more often […]

We said last week that it would be hard to predict what would happen over the next seven days – and that turned out to be true. The coronal hole we mentioned last week didn’t really amount to much, and sunspot region 2790 didn’t either. As a result, the solar flux index fell to 82 […]

What a great week it was for HF propagation. We started it off with the CQ Worldwide CW HF contest, which saw some DX openings up to 28MHz and solid DX being worked on 21MHz. The only downside was an M-class solar flare, which was launched off the Sun on Sunday. It was a big […]
