Solar activity increased this week. Average daily sunspot number went from 127.7 to 197.4 and average solar flux from 170.5 to 240.2.

Predicted solar flux is 270 on November 1-2, 265 and 260 on November 3-4, 250 on November 5-7, 214, 195 and 182 on November 8-10, 172, 168, 174 and 165 on November 11-14, and 162 on November 15-16.

Predicted planetary A index is 5, 8, 15, and 10 on November 1-4, 5 on November 5-15, then 5, 8, 5, 12, and 8 on November 16-20, and 5 on November 21 through December 5

Weekly Commentary on the Sun, the Magnetosphere, and the Earth’s Ionosphere – October 31, 2024 from OK1HH:

“We know only approximately what the Earth’s ionosphere looked like between March 1755 and June 1766 thanks to observations of the Sun in Solar Cycle 1. But we do know what it looked like in Solar Cycle 19, which ran from April 1954 to October 1964. Although I was a novice radio amateur at the time, I can testify that the shortwave propagation conditions at the peak of Solar Cycle 19 (1958) were wonderful!

“As of December 2019, Solar Cycle 25 is in operation. It was supposed to be low, fortunately it is not. Its maximum is now underway, perhaps a second will follow next year. It is fabulous, judging by the above and the many interesting effects, including, for example, auroras. But unfortunately, not if we judge them by the current conditions of ionospheric shortwave propagation. An explanation of why this is now the case will surely be forthcoming – but perhaps Solar Cycle 26 will be underway.

Predicted planetary A index is 5, 8, 15, and 10 on November 1-4, 5
