Juno, the marriage asteroid, enters Sagittarius on November 6th. Concepts of commitment expand. The definition of monogamy is not as structured in this sign, but it becomes more idealistic.
As the archetype of formal commitment (and associated power balance) Juno in Sag can bring up theoretical pictures of what an ideal relationship looks like. The distant, rosier vision of a relationship's future can be something to shoot for, with the caution that some of these ideals may be impossible to attain. The resulting disappointment of a failed contract (even if it's unwritten) can trigger Juno's angry, judgemental side. Relationship justice and law may be emphasized.
However, this transit can open up the lines of communication and possibility in a partnership- power imbalances can be addressed, differing views on fidelity can be explored. Freedom for one or both partners is very important for relationships that begin under this transit (if Juno in Sag makes close aspects to the natal charts).
Juno will exit Sagittarius for Capricorn on February 3rd, 2017.
