Hello, Ash!It could be major, it could be nothing in particular. Juno can be about signing contracts. I remember signing a contract when Juno was conjunct my POF.
Or it could be that you will meet your future husband/wife.
Only you can tell us, after it happens.
I know this isn't reassuring at all, but sometimes transits we expect with great anticipation go by us uneventful. Other times they are exactly what we imagined they would be.
Keep us posted.
