Mercury Trine Retrograde Saturn...

starts on February 12 (using a 1 degree orb), is exact on February 13 at 12.34pm, leaves on February 14.  Mercury at 3 degrees and 50 minutes of Aquarius, retrograde Saturn at 3 degrees and 50 minutes of Libra.

Mercury, the planet associated with communication, our thinking and also with how we 'connect' to the world around us joining forces with Saturn suggests a bit of a serious tone, but also the opportunity to make long term plans.  The trine aspect is a flowing and easy-going one that removes blockages, so it looks like the people and situations represented by these planets in your birth chart should connect easily and make progress.

Saturn is retrograde, this suggests that even though the people and situations represented by this planet may be regressing, that this will ultimately be a positive process.  The Mercury/Saturn trine suggests that you will now have the chance to sort through and understand a situation from the past (Saturn retrograde).

By looking at where this trine is happening, and which houses are ruled by Mercury (ones with Gemini or Virgo on the cusps), and Saturn (ones with Capricorn or Aquarius on the cusps), you will get a better idea of where progress can be expected. 

If you have personal planets/points in Libra and/or Aquarius then you are likely to feel this aspect more than others.
