Sun Square Saturn...

starts on June 18 (using a 1 degree orb), is exact on June 19 at 11.18pm in Kilmore, leaves on June 21.  Sun at 28 degrees and 9 minutes of Gemini, Saturn at 28 degrees and 9 minutes of Virgo.

The Sun tends to energies whatever it touches and highlights and acts as a 'trigger' for some of the longer term energies that are around.  In this case, the Sun accentuates Saturn.

Because the aspect between the Sun and Saturn is a square, this suggests tension - but a turning point... sometimes the only way we get motivated enough to do something about a situation is when it annoys us enough to do something about it!  That situation that causes us enough annoyance is likely to be something or someone represented by Saturn in our birth charts (look to see where it is travelling, and also which houses have Capricorn or Aquarius on the cusp to get an idea).

The square is a waning one, so we may need a shift in attitude to the people and situations involved in order to make progress.

As usual, look to see where this aspect is falling in your birth chart and which houses are ruled by the planets in order to get a feel for what, or who, may need a new attitude or approach.  If you have personal planets and/or points in Gemini and/or Virgo then you are likely to feel this energy more than others.
