Propagation News – 13 November 2022
Last week was a mixed bag in terms of space weather. Yes, the solar flux index increased to 138 by Thursday 10 November, but at the same time we had a fast solar wind and a solar flare from active region AR 3141 to contend with. The Kp index hit five on Monday 7 November […]
Propagation News – 06 November 2022
We had yet another week of good HF propagation, despite a strong solar wind that threatened to push the geomagnetic Kp index up, but it generally never managed more than a four in the first half of the week. The solar flux index managed to hit 130 on Thursday, having been in the 120s all […]
Propagation News – 30 October 2022
Good conditions on HF have continued with only a short geomagnetic disturbance to dull things a little. The planetary Kp index got up to five on the 25th, due to plasma from a geo-effective coronal hole, but luckily it recovered quite quickly. Two days later it was back to one and the upper HF bands […]
Propagation News – 23 October 2022
We had another great week of HF propagation, helped no doubt by a very low geomagnetic Kp index meaning the ionosphere remained settled. Despite the solar flux index declining to 113 by Thursday, 10m has been highly active with openings every day. We have had good daily 10m openings, even out as far as the […]
Propagation News – 16 October 2022
We had yet another week of good HF propagation, helped by reasonably settled geomagnetic conditions. Although the week started relatively poorly with a Kp index of four all day on Sunday, that soon improved slightly and the rest of the week saw the Kp index hit only ones or twos. The solar flux index declined […]
Propagation News – 9 October 2022
Yet another good week for HF propagation has passed, although it has been borderline in terms of geomagnetic disturbances. The Kp index hovered around the four mark all week, mainly due to high-speed streams from the solar wind, possibly from slight glancing blows from incoming CME material. There have been a few M-class solar flares, […]
