Sun Conjunct Mercury...

starts on October 16 (using a 1 degree orb), is exact on October 17 at 12.05pm in Kilmore, leaves on October 18.  Both at 23 degrees and 33 minutes of Libra.

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 Libra on the cusp in order to get a feel for where a new start is needed.
