Last week saw the solar flux index decline very slightly to 137. The good news is that we have had reasonably-settled geomagnetic conditions. The highest Kp index has been three, but it has often been at zero or one. This is good news as it means that the ionosphere has had a chance to develop. […]

We had an expected boost to the solar flux index last week, thanks to a returning sunspot group. This, when added to sunspot region 3098, pushed the SFI to 152 on the 11th. The returning group, which has now been updated to active region 3102, isn’t quite the threat it was on its last visit, […]

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 […]
