Dear Marcel de Bont, theartist, Vancanneyt Sander, Emilio Petrozzi, Mr.Fractal
Thank you for all the great posts! I am a newbie amateur that became interested based on some of the media accounts of work in this space. Those models had somewhat divergent predictions of future sunspot activity- Cycle 25. As a Ph.D. in another field (Chemical Engineering) I find all this fascinating. The fascination is probably spurred by my late father, who was an outstanding amateur astronomer.
And then you have the sun spot history itself. It was "corrected" (I use quotes because I have no idea if I think it was appropriate) in this work described here:
Any idea what was the basis for correcting this (in laymen's terms)? How it was done and why the "corrected" data is more believable than the original data? It shows no increase in solar activity, yet, other accounts have recent solar activity at a 8000 year high
My laymen's take: solar behavior is poorly understood, but the next 5 to 15 years could be an opportunity for significant advances. Even less understood is the impact of solar activity on climate.
