The 2nd of the Uranus/Pluto squares is coming up on September 19th (at 6 degrees Aries and Capricorn). It will involve Mercury at 3 degrees Libra, opposing Uranus and squaring Pluto.
Balanced, sociable communication (Mercury in Libra) will be the goal. But it's gonna be tough...opinions will be challenged and confronted at every turn. I'd say disagreements are a given with this aspect. But rather than hiding, say what you need to say. Expect surprising reactions (Uranus) and challenges/power plays (Pluto). Much of this may come out of nowhere. Just play it cool. Mercury in Libra is light on his feet, so use that to your advantage.
Remember what this square is all about; change. So roll with it and consider all incoming opinions. Could some of them be valid? You're open to anything new, because you're all over this Uranus/Pluto evolutionary thing. Now, this is not the same as rolling over and exposing your belly in submission. Remember that Libra is the Iron Fist in the Velvet Glove. Politeness with a core of steel. You'll hear what others are saying, but you don't have to agree with everything.
Those with planets between 3-6 degrees Aries, Libra and Capricorn will be in the thick of this one. Mercury will form an exact square to Pluto and opposition to Uranus on September 20th.
