The 66.5 reading is the lowest so far in the solar cycle 24 down slide
towards solar minimum. At solar minimum the daily solar flux number stays in
the low to mid 60’s range for years at a time.
Solar minimum may begin later this year and may last longer than any
previous solar cycle in the 20th century. When solar cycle 25 finally gets
going it could be the weakest since the middle of the 19th century. Another
Dalton type solar minimum may occur with a corresponding cooling of earth’s
climate. This would negate anthropogenic climate change if it were occurring
On February 1, 2008 I forecasted that solar cycle 24 would be the smallest
solar cycle in the past 100 years. That forecast verified.
I also forecasted that solar cycle 25 would be almost non nonexistent.
Note! I use error prone RAW public domain data from the NOAA Space
Environment Center, other U.S. government entities and educational
institutions, to produce this solar cycle 25
forecast. This data is gathered and made public by the U.S. Government using
taxpayer $$$ (including mine).
However this solar cycle 25 forecast that I have produced from the RAW
public domain data is my personal intellectual property. Therefore this

Feel free without prior permission to redistribute this solar cycle 25
as long as you redistribute it in its entirety and

Solar cycle forecasting is still an inexact
science and therefore also an art. The forecasts are not official but for
educational and hobby related purposes only and are subject to human error
