Solunars by Aldebaran Sidereal Academy

Recent discussions in other threads this week have returned attention to a little-examined approach to synastry, which is aspects by parans. I'm skeptical of the value of these, yet agree they should be explored - simply because they never have.

This brings several complexities. One important complexity, that Mike's TMSA software will resolve, is that one chart has to be precessed to the date of the other so they are on the same playing field. Another complexity is the question of location: While the related-but-quite-distinct mundoscope-to-mundoscope comparison needs to be done inside the framework of one of the charts (and then switch), the paran comparison brings the question of location: The charts need to be for the same latitude. It makes most sense to make this for the location where they both live. (If they don't live in the same location, I'm not sure there is a basis for a paran comparison.

As a single example to demonstrate the approach, I'll compare Marion's and my chart - using the local charts for our home, 34N03'46", 118W18'47". We will pretend that one has been precessed to the other (they have not - but the accrued precession is less than 0°07'). I also have not layered in all the RA squares to meridian (but I think these should be included in a full list approach, or treated separately to get RA squares).

Here is my local speculum. (I've marked partile parans in bold.)

Here is Marion's local speculum (again with partile parans marked in bold):

Now I will visually scan the two lists side-by-side for any contacts within 2°. (We can always trim this back to 1°. By using 2°, either planet can be within 1° of an angle with the other.) With today's software, this is a tedious task, but not hard.

J Plu Asc 46°09' -- M Sat Dsc 45°30'
J Ven IC 52°10' -- M Mar Asc 51°26'
J Mer Asc 140°55' -- M Nep Asc 141°36', Ven Dsc 141°47'

There is a good thing or two to say about this list, but in general I'm not impressed. (It matched my negative expectations on the system.) This is especially because the last two are also ecliptical aspects that I already know are valid.

While I'm giving the example, I should see if there are any squares in right ascension. For this, I only need two entries per planet: One where it is on MC, one where it is on EP. (The conjunctions and oppositions have been absorbed into the paran search above.) - These are often-missed parans, co-angularities on adjacent angles of the MC-EP-IC-WP set. In this case, there aren't any.

In contrast, using the same 2° orb, here are the standard ecliptical aspects. (I'd normally use more than 2° for these aspects - there would be more, and more significant ones, such as my Venus on her Dsc 3°00' - but I want a level playing field for comparison to the above aspects.)
