Propagation News – 11 September 2022
What a week we have just had! The Kp index stayed at four or more for most of the week thanks to an enhanced solar wind stream. This continued to stir up geomagnetic activity with minor ,G1, storm conditions. Visible aurora have been reported at higher latitudes. Sunspot region 3089 has now rotated behind the […]

The radio propagation report was compiled by G0KYA, G3YLA, and G4BAO on Friday the 2 September 2022. Many amateurs thought Christmas had arrived early when a solar flux index of 252 was posted on the 28th of August. This would have been representative of a very good solar maximum. Unfortunately, it wasn’t to be as the […]

There was a welcome upturn in ionospheric propagation this week, with much DX being worked. While the solar flux index remained mainly in the low 100s, quieter geomagnetic conditions, with the Kp index at one or two, helped a lot. We are also heading towards September and better propagation conditions as the ionosphere cools down, […]

It looks like the Sun continued to be unsettled with an enhanced solar wind from coronal holes making itself felt here on Earth. A geomagnetic storm pushed the Kp index to six for two consecutive six hour slots on the evening of the 17th, although it was fairly quick to recover. However, it wasn’t long […]

The geomagnetic disturbance we predicted last week, due to an Earth-facing coronal hole and its associated high-speed solar wind, occurred in the early hours of Monday the 8th. This pushed the Kp index to six and sparked a visible aurora that was visible from parts of the UK. It also impacted the Maximum Useable Frequency […]
Propagation News – 7 August 2022
Last week was characterised by a solar flux index around 100, but reasonably settled geomagnetic conditions. The SFI had a low of 94 on Sunday and a high of 100 on Thursday. The Kp index has been in the range of one to four, with more settled conditions being experienced in the second half of […]
