Steve, I'm not sure I understand your question, but ISteveS wrote: ↑Sun Feb 10, 2019 8:54 amPertainingonlyto the 360 Circle of the Precession Cycle is this Precessional Circle perfectly squared with 4 90 degree quadrantsonlywhen 00,00 degree of the Cardinal Points in the Sidereal Z areexactlycnj the Vernal Point? I can see with astronomy discussed in this thread the astronomy involving these Circles are perfectly squaring out with 4 90 degree quadrants with charts my eyes see, but what is happening to the astronomy with the Precession Cycle when 4 times in c. 26,000 years the exact zero points of the Cardinal Sidereal Ingresses are exactly cnj the Vernal Point, or does this matter with the context of this thread?

*think*I know what you're asking, so I'll take a whack at it.

**At all points**in the 26,000-year cycle, and

**everywhere on earth,**the following is invariably true:

Whenever either equinoctial point is exactly on Ascendant, the solstice points (which are exactly square the equinoctial points) are on the meridian and the Antivertex-Vertex axis has exactly the same longitude as Asc-Dsc.

As I write this, the SVP is 4°59'48" Pisces. Therefore:

* The vernal equinoctial point is 4°59'48" Pisces

* The autumnal equinoctial point is 4°59'48" Virgo

* The summer solstitial point is 4°59'48" Gemini

* The winter solstitial point is 4°59'48" Sagittarius

Therefore, for all places on the world today, the following things are true:

1. If 4°59'48" Pisces is on Ascendant, the MC will be 4°59'48" Sagittarius and the Vertex 4°59'48" Virgo.

2. If 4°59'48" Virgo is on Ascendant, the MC will be 4°59'48" Gemini and the Vertex 4°59'48" Pisces.

For example, let's see when one of those times was today for Springville, AL, using 33N46'30", 86W28'18". The VP 4°59'48" Pisces rose at 8:24:23 AM. (Set up a chart for any time today in Springville, click the Rectify button, and put

*4 Pi 59 48*in the Asc box. Understanding that calculating a chart to the nearest second of time gives you angles with a possible error of up to 15" (1 second of time = 15" on the angles), calculating a chart with Solar Fire for this exact time, longitude, and latitude gives:

Asc 4°59'59" Pisces

MC 4°59'55" Sagittarius

Vx 4°59'53" Virgo

The few seconds difference (11", 7", 6") are rounding errors, but I assure you that they all hit 4°59'48" at the same moment. Do a chart for 1 second earlier (8:24:22 AM) and you'll get angle positions ending in 36", 41", and 43", respectively (try it and see) - it's a rounding error. Somewhere around 8:24:22.52, these were all exactly 4°49'48".

Then test again for yourself but with the autumnal equinox rising, 4°59'48" Virgo. Do it yourself but, so you can check your work, I'll tell you the time is 8:22:25 PM. Test if for other locations if you like, or for Springville for different dates (get the new SVP each time). You'll see that the above remains true.
