This is such a great aspect in that you can feel like you are on fire!  Not literally, but mentally, things may feel as though your thoughts and words, how you express yourself, are clicking, and you find that you can think clearly in the couple days this transit will affect.  With Saturn involved, anything you sign now will be for the long term.  It is possible that, in communication, there is a rather large age difference between you and your audience.  This is not a frivolous aspect, and you will take seriously discussions happening at this time.
