re: Explaining the 5/4's progression rate between S/R charts

[Guest guest]

Here are some thoughts on the subject of the PSSR I wrote a

while back. I have been pondering this same question for

years. It makes the most sense to me when I think of the PSSR

as a simple cyclical chart such as a lunar return, and not any

kind of symbolic progression. The " progression " is simply a

means of identifying fractions of the cycle. Great minds have

disagreed with me on this.

 

---------------------

 

The solar day is reckoned from one transit of the sun over the

observer's meridian to the next. Sidereal time days are

reckoned from the Vernal Equinox point, which is much further

away, like a star.

 

The solar day exceeds the sidereal day by 3 min 56.56 seconds

of time on the atomic clock. This is due to the nearness of

the sun and the earth's orbital motion around it. The earth

has to rotate more than 360 degrees relative to the equinox

point to complete a solar day by bringing the sun back to the

observer's prime meridian.

 

56.56/60=.9426666 [convert to decimal minutes]

..9426666+3=3.9426666 [decimal minutes equivalent to 3m 56.56sec]

 

The solar day exceeds the sidereal day by 3.9426666 minutes.

 

3.9426666*365.24219=1440.0281834 [min per solar day times days

per solar year equals minutes per year that the solar day

exceeds the sidereal day.]

 

1440.0281834/60=24.0004697 [minutes divided by minutes per hour]

24.000. [hours per year that solar time exceeds sidereal time]

Here is the reason for the 24 hours. It is the cumulative sum of the

average daily difference between sidereal time and solar time.

" Equinoctrial time " is lagging tropical time by 24 hours at this point.

 

Each tropical year the earth rotates 365 and 1/4 times on its

axis. So the _approximate_ angular increase, discarding whole

rotations for each day of 360, is 24+6=30 hours from year to

year. This is the same as 1+1/4 rotations or 360+90=450

degrees increase for the sidereal cycle.

 

450/365=1.232876712

1.232876712 degrees per day of " progression " or angular

increase to be added to

the MC per day. This is an average rate only.

ADDED nov 02:

 

The sidereal year is 365.25636 days Filby

The tropical year is 365.24219 days

 

6.153 hours average increase in clock time for a sid. return.

5.813 hours average increase in clock time for a tropical return.

 

 

reality check on the PSSR. If you know different, please let me know.
