Sun Conjunct Mercury...

starts on June 12 (using a 1 degree orb), is exact on June 13 at 9.44am in Kilmore, leaves on June 14.  Both at 21 degrees and 39 minutes of Gemini.

Whatever the Sun touches tends to come into prominence in our lives,and the conjunction is a powerful connection that suggests the end of something old, and the beginning of something new.

Mercury represents our thinking, attitude and ability to communicate in general with the world around us, and also to connect with it.  Personally, it represents the people and situations as shown by which houses are ruled by it (house cusps with Gemini or Virgo on them). 

Also look at the house that the conjunction is falling in, and the one with Gemini on the cusp in order to get a feel for where a new start is needed.
