Mercury Trine Retrograde Pluto...

starts on July 30 (using a 1 degree orb), is exact on July 30 at 8.04pm in Kilmore, leaves on July 31.  Mercury at 3 degrees and 17 minutes of Virgo, retrograde Pluto at 3 degrees and 17 minutes of Capricorn.

Mercury represents the style in which we connect and communicate with the world around us, whilst Pluto is associated with depth and emotions, as well as uncovering the 'truth'.  The trine aspect is an easygoing one that generally helps the energies work together productively and removes barriers to progress that were a problem in the past.

By looking at where this aspect is falling in your birth chart you can get a feel for what and/or who may be flowing more smoothly than usual and where you can expect progress.  You can also get a feel for where you can gain a deeper rapport and understanding that goes beyond simple logic.

Also look to which houses are ruled by Mercury (ones with Gemini or Virgo on the cusp) and Pluto (one with Scorpio on the cusp) to get a feel for where you can expect progress.

If you have personal planets and/or points in Virgo and/or Capricorn you may be more sensitive than others to this transit.
