So with my Sun Taurus in ninth house trine Ascendant Leo trine Uranus Sagittarius in fourth house (scorpio on the cusp) I have which talent??? Center of attention in foreign countries? Or if I move to a foreign country?
An exact (0-degree-orb) trine always involves the three zodiac signs which share the same "element", fullmoonlibra - So, the "within-orb" Sun in Taurus will make your trine behave slightly differently to the "pure"
Fire Trine that you would have if Sun had been in Aries.
With a (pure) trine consisting of the three fire signs, you would have a talent for "enthusing/motivating" others (fire element); tend to be assertive/take-charge (positive nature) - and possess all three of the sign "qualities" (cardinal, fixed, mutable) required to initiate, pursue and complete projects.
With your trine - there are two pure-fire signs, two pure-positive signs and no pure-cardinal quality - whilst one earth sign, one negative sign and another fixed sign have been added to your "talents" - and the effect of this is to make you more practical (Earth), more a "worker than initiator" (fixed) and less-inclined to take-charge of others (negative).
