Solar scientists come up with another “method” for predicting the Sun’s future sunspot activity
The uncertainty of science: Using archival data from the last four sunspot cycles, solar scientists think they have found a new method for predicting the Sun’s future sunspot activity, based on what they claim is a “switch-off” moment in each cycle when the most extreme solar events stop happening.
The new prediction method builds on Professor Chapman’s previously developed ‘sunclock’, which maps the Sun’s irregular cycles onto a standard clock. This revealed that the most extreme space weather does not gradually fade away but instead switches off at a distinct point in each solar cycle.
Professor Chapman’s team has found that the number of sunspots present at this switch-off point is closely linked to the peak number of sunspots in the following solar cycle. This provides a new forecasting method that can predict the strength of the next solar cycle around six to seven years before it reaches its maximum, giving a longer lead time than current methods, which rely on waiting until the solar minimum.
Sounds good, eh? I would not bet one plug nickel on this prediction method. It might work, or it might not, but even if it does, it is not based on any real understanding of why sunspots rise and fall every eleven years. Nor does it explain why the Sun’s magnetic field flips polarity in line with that sunspot cycle. This prediction is merely using past behavior to predict future actions, a method that every stock broker will tell you is fraught with danger.
Knowing however that there is a moment in each cycle where the most active sunspots and solar flares stop happening is useful. This pattern could help theorists figure out what is really going on inside the Sun.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Very interesting to say the least!
