The solar flux index took a downturn this week, ending up at 150. The visible solar disk is looking rather bare compared with a couple of weeks ago. This is the lowest SFI value since the 2 May 2024, but it is only a matter of time before we see another sunspot appear as we […]

We had another week of high solar flux and good conditions on HF. Solar activity remained at high levels thanks to an impulsive X2.3 solar flare around active region 3883 at 13:40 UTC on the 6 November, but the event was not responsible for a coronal mass ejection (CME). The Kp index remained below 4.5 […]

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 […]
