See post #12 in this thread - I have included the USA chart with my markups ...
Let me explore and see what my curiosity and general observation will lead me to.
I am using the version of your USA chart, (But I recasted in with 10 minutes different with your version, see MC as 25 degree 35 minutes that is the closest I could get) which Jupiter returned on 22-23rd July which
could be essentially important as the chart ruler returned. I don't have the program to cast the exact Jupiter return chart.
But perhaps other advanced mundane astrologers can tell me if Jupiter Return chart could be a valuable information?
On the day of Jupiter return, ruler of Jupiter, Moon was in Capricorn which is US natal 2nd house. Moon is the natal ruler of the 8th house or debt and other people resources. And Venus was at the critical degree of Leo about to enter Virgo over the natal 9th house oversea connects. Venus is the natal 11th house ruler which is US's allies. On the return day, transit Mars was in Cancer, conjuncted transit Jupiter and Lilith on the natal 7th house, the open enemies. Mars is the natal ruler of 5th the house of Risk and traditional ruler of 12th house, faraway places, and self undoing, asylum seekers.
At this point, I am actually wondering what would the transit Uranus in Aries does when he conjuncts the natal Chiron in the 4th house while transit Pluto would be in the 2nd house for a very long time.
On the 3rd November 2013, Solar eclipse will be at the 11 degrees 16 minutes Scorpio which should be the midpoint of transit North Node/Transit Mercury Rx 7 degrees 26 minutes and Saturn 13 degrees 53 minutes. This solar eclipse will be close to be the antiscion of progressed Mercury Rx at 20 degrees 26 minutes but not exact so not sure how relevant.
The antisicia of Sagittarius is Capricorn, so when Pluto in Capricorn hits the 22 degrees of Capricorn, Pluto will be the antisicia of US natal ascendant.
