These two graphs indicate that there are times when solar
minimum occurs at or near the same location on the ecliptic.
When the Sun’s acceleration decreases during an Ice-age cycle
it’s orbit becomes more circular and average solar cycle length
becomes longer (approaching 11.86 years).
During the 12,000 year inter-glacial periods there is evidence
that this is happening to a lesser degree. Notice the 143 year
separation (Bretagnon wave?) between 1843 and 1986.
