Sun Square Saturn...

enters on July 2 (using a 1 degree orb), is exact on July 3 at 10.17am in Kilmore, leaves on July 4.  Sun at 10 degrees and 46 minutes of Cancer, Saturn at 10 degrees and 46 minutes of Libra.

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).

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 Cancer and/or Libra then you are likely to feel this energy more than others.
