Sunspots end of April, 2023. SC23-SC25. Back on the SC24 track?  Why 24 days? Be gentle .... |

Great thread on twitter explaining solar processes via an explanation of why a cycle is 22 years (ie 2 cycles of 11 years) long.

The period between twin peaks in a solar cycle is called the 'Gnevyshev Gap'
So, there you have it!

Note cycle 12 and 13 and the dominance of the southern hemisphere across the entire 22-year cycle. Cycle 24 has already given us half of that. Will the South rise again?  But note, that it hasn't led since SC18. |

Acidolm, you point out for good reason there may a better measurement of the sun's activity than the maximum sunspot number and I guess you feel the number this year may be lower than Svalgaard's prediction. If so, do you have a prediction on what "Acidolm's Gap" might be?

The Mysterious 60-to-80 year Repeating Cycles we Talk About
I am re-posting this chart which shows most of our major ocean indexes in relation to the sunspot cycles ... and the hemispheric differences that Acid posted here. Perhaps it's coincidence ... but that is too convenient an excuse. As you can see, there are major index downturns in the linked second solar cycle of the 22-year Hale cycle ... focused on cycle 13, cycles 18 and 19, and cycle 25 (or 24 & 25). These seem to coincide with hemispheric shifts in dominance or magnitude within or across 22-year Hale cycles ... as shown in the charts that Acid posted. Solar Cycle 19 has always struck me as "particularly strange" in relation to other cycles. For example, chart 2 shows the ENSO 3.4 progression across the first 5 years of solar cycles 19 to 25. SC19 was the only cycle that did not have a pre-cycle El Nino. Very strange for a major solar cycle. SC25 just barely had one (in comparison to others). I find it hard to believe that these are merely coincidental. In aggregate, these time spans between major downturns are 60 to 70 years in length ... the mysterious repeating cycles we talk about occasionally.
The cumulative north & south sunspot totals for SC20 look way out of line (versus total sunspots) in comparison to other low solar cycles.

If you look at the SH and NH magnetic cycles they look to have slightly different periods, or period length cycles so in aggregate they show variability.

Cycle 19 is also highlighted in the paper I posted earlier..  |

Acidolm, you point out for good reason there may a better measurement of the sun's activity than the maximum sunspot number and I guess you feel the number this year may be lower than Svalgaard's prediction. If so, do you have a prediction on what "Acidolm's Gap" might be? Caveat....I'm just chewing information and analysing data because I do so compulsively. I'm lucky/grateful person's here share my interests and help by agreeing or constructively criticise, either is welcome! Currently my posts are in response to live data and I'm hypothesising on this. I don't see any gaps, it looks like the formation of a single peak. Possibly, we've past the peak, possibly not definitely. I offer no forecast on what any future peak may be, if the peak has past it is by default lower then svalgaards prediction. I havnt seen anything out there stating what I have, which is perhaps my neglect in searching enough. I may well be wrong in the outcome, time will tell. On the plus side, as I've got excited and looked more into the hemisphere side of things, hopefully some interesting info has been dredged out? |

Does anyone know if the plane of orbit of major planets in our solar system are oscillating from the horizontal enough that they may exert a phase shift on hemispheric tidal forces on the sun?
Here's bary again....been a while...

Thanks Acid. How do you spell that? Gap. G-a-p. I found a paper on the G-a-p by these authors G.A. Bazilevskaya, V.S. Makhmutov, and A.I. Sladkova so I decided to go watch TV. |

But note, that it hasn't led since SC18.
