Propagation News – 13 March 2022
We may not have had a large number of sunspots this week, but at least the Sun was consistent. We started the week last Sunday with a sunspot number of 116, and by Thursday it was still at 115. This sounds worse than it actually was as there were six sunspot groups active on Thursday, […]

We had another pretty uninspiring week, sunspot wise, with the solar flux index struggling to get above 100, at least until later in the week when it touched 110 on Thursday. The good news is that, on the whole, geomagnetic conditions were quiet, which really allowed the F2 ionospheric layer to develop. As a result, […]

It was not an outstanding week for HF propagation with low solar flux index numbers and an elevated Kp index at times. The week started off OK with the ARRL DX CW contest. This went quite well with 15 metres open as far as the mid-west in the afternoon, even for modestly-equipped stations. But with […]

Last week was pretty subdued in terms of sunspots, but it looks like we missed one of the most impressive space weather events of Solar Cycle 25. A bright, fast-moving coronal mass ejection, or CME, was visible coming off the far side of the Sun on imagery from the STEREO Ahead spacecraft. Had this event […]

We had a good week for HF propagation, with a solar flux index up towards 130 and relatively calm geomagnetic conditions. There were lots of reports of openings to Australia on 10 metres and the KQ2H repeater in up-state New York often put in an appearance on 29.620MHz FM as well. However, a Coronal Mass […]
Propagation News – 6 February 2022
We had another topsy-turvy week, with lots of good sunspots, but coronal mass ejections or CMEs taking their toll on the ionosphere as well. While the solar flux index did a little better than predicted, with numbers in the 120-130 range, there was bad news on the solar-terrestrial front. The Kp index was regularly hitting […]
