First, let's confirm the ecliptical transits. These will be different tropically and sidereally due to precession. (Rob normally adjusts for precession even while working in the Tropical zodiac, but I don't know if he did here.) The SVP when Hearst was born was 5°53'44" Pisces. At her abduction, it was 5°36'59". Therefore, 0°16'45" had accrued. (We could estimate this within 1' by noting she was in the month of her 20th birthday, subtract one-sixth of 20, or 20-3 = 17, so it was 0°17' of precession.)

Rob gave the following ecliptical transits according to Steve:

Sun 120 Jupiter -55’

Jupiter 90 Moon +14’

Neptune 90 Pluto -45’

I don't understand these at all! Transiting Neptune at 15° Scorpio is nowhere near square her natal Pluto at 30° Cancer. (This is not an artifact of the different zodiac.) Sun trine his Jupiter is there, but transiting Jupiter at 28° Capricorn is nowhere near square her Moon at 14° Virgo. Before we get too deep into this, I'd like to know if something is wrong - birth or event data wrong (it looks right to me at a glance) or Rob's results copied wrong, or I made a mistake. Nonetheless, since this is more about demonstrating technique than the actual results, I'll continue...

I get NO partile transits to her natal chart (which makes this a fabulous example!) except t. Moon conj. r. Uranus 0°51'. (One might count the EXACTLY 0°60' square of Venus to her Neptune.)

As a complete digression, here are transits to her SSR at the time. I include these to demonstrate that there were, in fact, important operative transits. I treat transits to the natal and the SSR as more or less equal, and a "transit profile" of the event isn't complete without these. Note, in particular, the doubled and reciprocal Mars-Pluto transits!

t. Pluto 90 s. Mars (0°31')

t. Uranus 135 s. Saturn (0°50')

t. Mars 135 s. Pluto (0°45')

Returning to the paran transits, and how to more easily calculate them to adjust for precession, here is a technique that works easily for paran conjunctions and oppositions, and is more tedious for the paran squares. Here is the list of paran aspects Rob gave, as quoted by Steve.

SunM 90 MarsD +54’

MoonM 0 UranusM +48’

MoonD 90 SaturnM +32’

MoonA 90 MoonI exact

VenusM 90 SaturnD -26’

VenusA 90 SaturnM +25’

SaturnA 90 VenusM -11’

UranusD 0 NepunteD -03’

Regrettably, most of these are squares, which makes my demonstration tedious; but that, in turn, demonstrates why paran transits are such a pain to calculate.

I'll start with those he cites that are not squares.

MoonM 0 UranusM +48’

UranusD 0 NepunteD -03’

Using Solar Fire, we need (1) the event chart and (2) the natal chart relocated to the event location (so that it has the same latitude). Since Hearst was born in Berkeley where the event occurred, we're good to go!

Open her natal chart in Solar Fire, click Pages, and select the page called Mundane Data Large. (It's the page file

*mund.pag,* and I think it's been in all versions of SF back to at least v5.) This shows the longitude of each angle when the planet is crossing it mundanely. Though it isn't a

*perfect* adjustment for precession, it will get us, in a normal human lifespan, within a few minutes in the worst conditions.

Extract the longitudes at which Heart's Uranus crosses the MC (CoCulm) and her Neptune crosses the Dsc (CoSet).

r. Uranus crosses MC 25°29' Gemini

r. Neptune crosses Dsc 4°43' Libra

Now, do the same for the event chart, but extract the longitudes at which transiting Moon culminates and transiting Uranus sets.

t. Moon crosses MC 25°58' Gemini

t. Uranus crosses Dsc 4°24' Libra

Look at what we can see! Transiting Moon crosses MC 0°29' later than natal Uranus. This is 19' closer than the 0°48' orb Rob reported (doing his calculations all Tropically), and the 19' gap is very close to the 17' displacement along the zodiac of precession since her birth. Also, t. Uranus crosses Descendant 0°19' earlier than natal Neptune; in this case, this is wider than the 0°03' orb Rob gave from Tropical calculations. The difference between the SZ and TZ paran calculations is 0°16' so, again, it is very close to the 0°17' of actual precession.

So much of the good news is: At least in this case, and in fact in a large majority of cases (at least in moderate latitudes) the actual shift in paran orbs will be within

*a very few minutes of arc* from what we would get by just applying precession corrections to a Tropical calculation of the parans. This is encouraging!

Continuing... how would we test and calculate the paran squares he gives? This is tedious but doable. Here is the list:

SunM 90 MarsD +54’

MoonD 90 SaturnM +32’

MoonA 90 MoonI exact

VenusM 90 SaturnD -26’

VenusA 90 SaturnM +25’

SaturnA 90 VenusM -11’

We can easily calculate (just like the examples above) the longitudes for which each is on each angle, but that doesn't help much. I'll pick one example to show in detail - say, the Venus-Saturn paran. Rob's table shows transiting Venus rising 25' from when natal Saturn was on MC.

Step 1: Calculate the longitudes where each of these crosses the angle, using the Mundane Data Large report. Transiting Venus rose at 23°47' Sagittarius. Natal Saturn culminated at 16°05' Libra.

Step 2: Find out how far the MC is from 16°05' Libra when 23°47' Sagittarius rises. For this, use Solar Fire's rectification option. Open the event chart, click Rectify, and, in the Asc box, edit whatever is there to 23°Sg47'. You don't even have to click OK and finish, just click into another box and, instantly, you see that MC is 16°14' Libra, or 0°11' from the longitude of natal Saturn when on MC (16°05' Libra). Conclusion: Transiting Venus was 0°11' from paran-square to natal Saturn at that moment. This is 0°14' close than the orb Rob gave, so, again, we know that if we just subtracted 0°17' (accrued precession) from his calculations, we would be very close to the sidereal value.

That's how you use SF to check these. Though now we also know that you probably are OK just subtracting precession from the Tropical figures and knowing you are a few minutes off. Of course, at my age, that means I'd have to calculate them with a 2° orb to get all the possible aspects, since precession has been 0°51' since my birth.[/quote]
