Propagation News – 30 April 2023
What a busy week we’ve just had! It started with a massive G4 geomagnetic storm that saw the Kp index rise to eight with aurora visible as far south as Cornwall and the Channel Islands. This was due to a coronal mass ejection from a filament eruption on 21 April. The 6m band came to […]

We had a surge in sunspot activity over the last week, pushing the solar flux index up to a maximum of 178, although it subsequently declined to 147. Solar flare activity was quite subdued after a frantic period from the 13 to the 15 April that saw 40 C-class flares and two M-class flares erupt. […]

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 […]

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 […]

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 […]
Propagation News – 26 March 2023
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 […]
