Propagation News – 18 November 2018
The predicted bad geomagnetic conditions forecast for last weekend didn’t turn out to be quite so bad after all. The Kp index only rose to four on the 10th and then conditions settled again, despite a large coronal hole on the Sun’s surface. However, reports did come in of poor conditions on 80 metres on […]

The large geomagnetic disturbance that we predicted last week actually hit the Earth on Sunday evening and Monday morning, as the plasma cloud was moving slower than experts predicted. Nevertheless, its effects were dramatic, pushing the Kp index to six and sparking widespread visible aurora, even from parts of the UK. The geomagnetic storm hit […]

Quieter geomagnetic conditions and a better autumn ionosphere meant HF conditions were quite good this week. GB2RS listeners reported plenty of DX activity during CQ Worldwide last weekend, including openings on 21 and 28MHz at times. While HF propagation was never going to be as good as it is at sunspot maximum, it does show […]

We were blessed with quieter geomagnetic conditions this week. And despite the solar flux index only being around 70, a more settled ionosphere meant there was DX to be had. The 6G’s VK9XG DXpedition to Christmas Island off the north-west of Australia has been worked on many bands from the UK, including 160 and 80m. […]

The sun remained pretty well spotless in the latter half of this week, with a solar flux index of 70 at the time this report was being prepared. But after an email from a GB2RS listener it is probably a good idea to recap how sunspot numbers are calculated. We count each sunspot as one, […]
Propagation News – 14 October 2018
Last week was not very good for HF propagation, with the effects of an enormous solar coronal hole, and its associated high-speed solar wind, sending the K-index soaring. There were, however, some upsides. The initial positive phase of a geomagnetic storm saw maximum useable frequencies rise to more than 21MHz during the afternoon and early […]
