I found it odd that nobody mentions the *positions* of the planets
(Jupiter, mainly), during solar max. Maybe to try to avoid the

Could there be some kind of effect from a tidal force on the sun
arising from the pull of the planets when they converge on a certain
pattern every eleven years?
That's the first reason one would think of. But, according to the one of
the references in the paper
<http://arxiv.org/ftp/arxiv/papers/1106/1106.0847.pdf>, a tidal effect
is ruled out due to its small magnitude:
"However, it was realized that the estimated planetary tidal impact was
extremely small to cause any significant change of the dynamic Sun [2],
or even less to justify the origin of the enigmatic 11 years cycle. For
this reason the planetary - Sun connection has been ignored for long
time, while such a claim was also seen not only within astronomy, but
rather instead within the frame of astrology [3]!"
