Leif Svalgaard of the W.W. Hansen Experimental Physics Laboratory at Stanford University -- a highly regarded solar physicist -- predicts solar cycle 25 SSN of 128 +/- 10. According to Svalgaard: "This prediction is near the average (123±21) of the 6 (now 7) precursor methods that seem to be preferred. The overall average is 132±47 (median 124). The overall average is 132±47 (median 124). None of these numbers are substantially different, so one could perhaps just go with the “Wisdom of the Crowd” (Aristotle, 350 BCE, “Politics”, III:xi; Galton, 1907)." " All predictions that we consider have the underlying assumption that the sun has not changed its behavior (its “spots” so to speak) on a timescale of a few centuries (the Maunder Minimum may be a possible violation of that assumption) and that there will be no such changes in the near future, in spite of speculative suggestions like in Livingston et al. (2010) and Svalgaard (2013)." wattsupwiththat.com/wp-content/uploads/2020/10/Prediction-SC-25-JSWSC-nl.pdf 73 Frank W3LPL _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
