I may take you up on that.

In future, I may look at Gleissberg cycle but that might be contentious. It appears you are not totally convinced by it either. Your FFT analysis shows clear ~108y, I have personal favourite (95 +118)/2 = ~107y, but there is a small flexibility there, and 108 is only an average.

How about Gleissberg and 107 year Vukcevic cycle? That is pure planetary technology, you gota the data I gota the formula, lets make something out of it.

Are you up for it?

W. Gleissberg In his letter (1945) Evidence for a long solar cycle

writes: " One long cycle is equal to 7 eleven-year cycles or 77.7 years. "

26 years later in his submission The probable behaviour of sunspot Cycle 21

to Astronomical Institute, University of Frankfurt/Main, West Germany

Received: 18 May 1971 Revised: 30 June 1971

Gleissberg states following:

" After an explanation of the method of forecasting based upon the 80-yr sunspot cycle, reasons are given for assuming that the maximum of the present 80-yr cycle now has passed. "

Considering above conclusion is that Gleissberg believed that the cycle bearing his name is 80 (77.7), and not 70 or 90 or 108 year long cycle.

If any of contributors to www.solarcycle24.com are aware of any articles or letters by W. Gleissberg quoting other values for 'long solar cycle' I would appreciate a quote or link if possible.

Thanks and appreciation is expressed in advance.

Most importantly FFT power spectrum analysis shows that there is noting there between 50+ and 100+ years. Many researchers use 'Gleissberg cycle' as if it is an accordion, stretching and squeezing to fit their requirements. Even Dr. Hathaway, in his latest work, quotes 8 cycle length against discoverer's 7cycles, since it suits better to his high prediction of SC24.
