Propagation News – 16 April 2023
A news item this week suggested that the peak of solar cycle 25 could be coming earlier than expected. According to a paper in Frontiers in Astronomy and Space Sciences, by solar scientist Dr Scott Macintosh, solar maximum may now be coming between late 2023 and mid-2024. So, make the most of the higher Solar […]
Propagation News – 8 April 2023
Solar activity declined this past week with the Sun looking distinctly spotless, other than active region 3270. In fact, this has even prompted some amateurs to question whether we are now past solar maximum for this cycle. Rest assured, we shouldn’t be, as it is pretty common for cycles to ebb and flow as they […]
Propagation News – 2 April 2023
We were right in our prediction about the effects of the large solar coronal hole last week, which saw the Kp index peak at 7.67 with widespread aurora visible from the UK, even in the south. This was probably the most significant geomagnetic event we have had so far in this solar cycle. Last week […]

The solar flux index dipped a little last week, down to 148, but it didn’t last long and was back up to 159 by Thursday 23 March. We were free of major solar flares with only one M-class flare occurring on the 20 March. Geomagnetic conditions were mainly settled as well, but that could change […]
Propagation News – 19 March 2023
Last week was split in two, in terms of HF propagation. The first half of the week was characterised by excellent high-band conditions, with many people commenting on how good things were. The Kp index was low, there was a lack of solar flares and the solar flux index was high—perfect for HF. There were […]
Propagation News – 12 March 2023
It was business as usual last week with the solar flux index in the 180s, numerous C-class flares and, at the time of writing, 13 M-class flares over the past seven days. The Kp index has been mostly settled for this part of the cycle, averaging two to three all week. But this doesn’t mean […]
