Unequal day length

The unequal noon cycle is due to a change in orbital orientation
attached to orbital motion.Extracting axial rotation to isolate the
orbital change in orientation is difficult however,using the observed
extreme axial rotational orientation of Mercury ,it is easy to
identify the change in orbital orientation as a seperate component -

This change equally applies to the Earth and replaces the pseudo-
dynamic of variable axial tilt to explain the seasons or the unequal
length in the noon cycle,For convenience,it is possible to split the
orbital orientation change in terms of the solar radiation/orbital
shadow boundary -

The boundary pivots off the Equator allowing for seasonal daylight/
darkness asymmetry North and South of the Equator and provides the
main reason for hemispherical weather patterns (seasons) as the length
of time a location spends in solar radiation and in the orbital shadow
of the Earth rather than inclination to solar radiation.

The longitudinal change in the solar radiation boundary is more
problematic as axial rotation has never been isolated as an indepedent
motion.The longitudinal change causes the noon cycles to globally
vary in length .Traditionally ,the variations in daylight/darkness and
the total length of the daily cycle have been bound up in the pseudo-
dynamic of variable axial tilt or inclination but as observations of
Uranus show,the causes are due to a change in orbital orientation.

I have already explained to s.a.a. forum where the copnceptual
obstacles exist in allowing astronomers to work with a new motion,,
which allows the planet a counter motion that is obscured by axial
rotation for the most part. I have also determined that it is a point
of rest for me,the convenience of splitting the orbital shadow/solar
radiation boundary into latitudinal and longitudinal components should
not obscure the actual appreciation of the new motion based on a
change in orbital orientation.In short,the images from Uranus should
be good enough to pursue its application to the Earth -
