Excerpt from my latest Sasstrology article (please leave comments on the Sasstrology site):
"I often get questions about the validity of out of sign aspects. For example, if your Sun is at 29 degrees Virgo, and your partner’s Moon is at 0 degrees Libra, some astrologers would consider this to be an out of sign conjunction. I’m one of the astrologers who would notconsider this a conjunction.Aspects involve the angle between two planets, and the signs they are in. You can’t ignore the impact signs have on planetary aspects, because planets and signs aspect each other."
