Propagation News – 7 August 2016
This week saw the effects of yet another solar coronal hole, which pushed the Kp-index to four and five on Wednesday and Thursday. We predicted this last week, but were out by one day. Lacklustre sunspot activity also meant that the IOTA contest saw many contestants staying on 20m and below, with the odd foray […]
Propagation News – 31 July 2016
This week we have been looking once again at a blank solar disk. The spotless sun offered a solar flux index of 72 on Thursday, just six points up from a typical solar minimum figure. Unfortunately, the bad news doesn’t stop there. There were poor geomagnetic conditions last weekend thanks to the effects of a […]
Propagation News – 24 July 2016
There was plenty of solar action this week. The solar flux index climbed to 108 on Thursday thanks to a slew of sunspots. Plus we had incoming plasma from a coronal mass ejection that sent the K-index up to five for nine hours in the early hours of Wednesday 20th. There have also been some […]

We got the HF prediction half right last week. We forecast the unsettled geomagnetic conditions that struck us on Tuesday, but NOAA got the week’s solar flux index prediction totally wrong. Prior to last Friday the sun had been almost completely spotless, but a new crop of sunspots broke out, pumping the SFI from the […]
Propagation News – 10 July 2016
We got the forecast for last weekend about right. Plasma from a coronal hole hit the Earth late on Saturday, pushing the K-index to four. The solar flux index, however, has remained doggedly in the 70s. DX has been possible on HF though. After a request for information last week Peter, M0RYB said he was […]
Propagation News – 3 July 2016
The Sun has had another virtually spotless week with the solar flux index keeping stubbornly below 80. As we said last week, this is getting close to the kind of figures we expect to see at sunspot minimum, such as when the SFI touched 64 in June 2007. Geomagnetically, things were a little more settled […]
