Propagation News – 15 September 2019
It was a quiet week, geomagnetically speaking, with the Kp index generally not rising above two. But a lack of sunspots didn’t help HF propagation, which was decidedly uninspiring. There were some highlights though, mostly on FT8. Columbia was decoded on Wednesday evening on 15 metres at a time when CW and SSB users might […]
Propagation News – 8 September 2019
Our prediction last week that there would be a major geomagnetic storm turned out to be correct, although we got the timing a little wrong. The solar material from a coronal hole actually hit the Earth in the early hours of Saturday morning, rather than later that day, sending the three-hourly Kp index up to […]
Propagation News – 1 September 2019
The past week was characterised by a low solar flux index and relatively-calm geomagnetic conditions. There were reports of numerous sporadic E openings this week that livened up the 10m band. On Thursday these spread from Serbia through to Germany, Finland and Norway and were probably caused by a strong jet stream, which can be […]
Propagation News – 25 August 2019
The last seven days have seen quiet geomagnetic conditions but, equally, zero sunspots and a solar flux index of around 67. Nevertheless, the Lighthouses on the Air event last weekend saw UK stations finding people to talk to, even if real DX was a little thin on the ground. Saturday, the 17th, saw numerous short-skip […]
Propagation News – 18 August 2019
We had more of the same last week with zero sunspots, but no geomagnetic disturbances. The good news is that there appear to be no Earth-facing coronal holes coming around the Sun, although there are significant holes around the solar polar regions. The tool at Propquest.co.uk has been showing an interesting phenomenon over the past […]
Propagation News – 11 August 2019
Matter from a solar coronal hole hit the Earth last week as predicted. However, we got the date wrong, as it actually impacted us on Monday and not Sunday, as it was moving slightly slower than we thought. This sent the Kp index up to five as the Earth’s geomagnetic field was disturbed and where […]
