The Full Moon (at 28 degrees Aquarius) is on August 20th. Mercury (communication/intellect) at 24 degrees Leo is sitting close to the Sun (opposing the Moon). I see this as the culmination of an idea.
Aquarius is detached, Leo is not. Aquarius is "the masses", Leo is that one, special person. Announcements/decisions/messages will come from a personal place (Leo) but will be sent out into the public realm (Aquarius). The first thing that comes to mind is a major promotion of something that is precious to you. A culmination of your creative energy/special project, that you launch on the internet (or some other public forum). That's your baby (your creation) you'll be throwing into the unpredictable, Aquarian public. Or, you may get a surprising answer to some dramatic/romantic statement (marriage proposal/revelation of feelings) .
The Jupiter/Uranus square will be exact a few hours later (on the morning of August 21st). All that hyped-up, emotional energy will be at a peak. But so will the potential for sudden success. This will be a risky Moon (Uranus rules Aquarius), with no guarantees. Leo likes to gamble, so this could be the moment when you bet everything on that one email/conversation/idea. But Jupiter will also be forming a soothing trine to Chiron in Pisces; this suggests supportive energy, if you put yourself out there (personally or professionally). Even if things don't go exactly as planned (and they probably won't), the Jupiter/Chiron trine suggests that you'll be able to roll with it. Just remember to let go of your ego (Leo), as much as possible. I know that's difficult, but with Uranus/Aquarian energy dominating, you'll do better if you can detach a bit.
Say it, then step back.
You'll feel this Moon most strongly if you have planets/angles from 24-28 degrees Leo or Aquarius.
