Two trips around is 80,000 km or about 50,000 miles! That's quite a trip. But how about 3 times around? Or more?
Thanks to John EI7GL and to Salvador EA5Y.

Thanks to Steve Wright EI5DD. I had the great good fortune of running into my friend Michael EI0CL on the 17 meter band recently. Mike mentioned that he had been talking to Steve. So Steve is in good company.
This Wired article has some really interesting info on competing theories about the solar cycle, about the danger to the Earth from solar flares, and about what a flare like that of the Carrington event could do to the transformers we are currently using. The article points out that large capacitors could protect these transformers from the effects of the flare. But the power companies are not installing the capacitors.
I think one of the scientists Pete mentioned in SolderSmoke podcast #238 is mentioned here:

PETE'S BENCH:
Phil W1PJE managed to hear and record some of the 2021 transmission (Thanks Phil). Listen here:

Phil also sent this spectrogram of the signal.
Their Solar Cycle Progression page is up-to-date. With the slider below each chart you can go back as far as 1750. Check out Cycle 19. I was born near the peak (TRGHS). Pete was on the air during that cycle. Cycle 23 also looked pretty good. I was out in the Azores then (2000-2003) -- no wonder I could work VK and ZL with a 5 watt DSB rig.
I like the little solar conditions widget that has appeared in the left hand column of this page, and I am grateful to the provider, but the widget just doesn't update regularly. So I think I'm going to switch to a link from the Space Weather Prediction Center that shows the numbers we really need: Solar Flux Index (SFI), Sunspot Number (SN), A index, K index. (Please let me know what you think about this change.)
Here is the link to the Solar Cycle Progression Charts (be sure to use the sliders):
