Propagation News – 18 June 2023
We had another week of sound HF propagation, helped by relatively quiet geomagnetic conditions, a lack of bad solar flares, and some good multi-hop Sporadic-E openings. The Kp index never rose above three and was mostly ones and twos. This was no doubt helped by no M-class or higher solar flares and no Earth-directed coronal […]
Propagation News – 11 June 2023
Solar activity has remained at low levels over the past few days with only minor C-class and one M-class flare detected. The majority of these small flares were produced by active region 3327 in the southeast quadrant. But a large number of sunspots means we are at a high risk of M-class or even higher […]
Propagation News – 4 June 2023
We had a relatively calm period last week with the Kp index remaining below three and plenty of sunspots. Although we started the week with the Solar Flux Index in the low 150s, it quickly picked up to reach 161 by Thursday. As a result, there was DX to be had, although most of the […]
Propagation News – 28 May 2023
The Sun currently has an equal number of spots in both its Northern and Southern hemispheres. The Solar Flux Index was consistently in the 150 to 160s range last week, with a total of eight M-class flares. We had unsettled geomagnetic conditions on the 21 and 22 May when the Kp index hit six, but […]
Propagation News – 21 May 2023
After last week’s NOAA prediction that we would have settled geomagnetic conditions all week, it seems they were right! The Kp index never got above three – a miracle given the recent disruption due to coronal mass ejections and coronal holes. The proton flux from the Sun has declined as well. However, an M9 solar […]
Propagation News – 14 May 2023
Our topsy-turvy world of HF propagation continued last week with geomagnetic storms, solar flares, coronal mass ejections, proton events and more. The good news is that the solar flux index was at 170 by Thursday, but the bad news was that we had two episodes where the Kp index hit five and there were at […]
