Last week was defined by a lack of sunspots, but otherwise reasonably settled geomagnetic conditions. However, towards the end of the week, the Sun woke up with regions 2797 and 2798 becoming active. The sunspot number rose to 25 on Thursday, although the solar flux index remained in the 70s, reaching 77 on Thursday. This […]

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 […]
