Caitlyn Jenner announced her name change as transiting Jupiter (the planet of confidence) was conjunct her natal Pluto (the planet of transformation) and transiting Saturn (the planet of endings) was square her natal Mars (the planet of male-ness). One newspaper headline is "Bruce No More".
Pluto is disposed by the Sun in Scorpio (ruled by Pluto) conjunct her ascendant. Jupiter transiting the chart ruler indicates a huge transformation and one can't change one's appearance more than changing genders!
It is also interesting that her natal Mars is at 0 degrees Virgo, a combination known for its need for perfection. Transiting Saturn in Sagittarius (ruled by Jupiter!) square the natal position of Mars shows a great determination to overcome boundaries. Again, one can't push the boundaries more than a former Olympic gold medallist deciding he wants to be a woman seemingly out of the blue.
Progressed Mercury, the ruler of her natal Mars is conjunct her natal Moon in Aquarius. Well it is IS something different, against the norms and like all things Mercurial, it's getting people talking. And just check out transiting Uranus over her natal worth Node!
Wishing Caitlyn all the best luck in the world on her journey.
