Solar Arc Directions
Definition
A predictive astrology technique that advances every point in the natal chart forward by the same arc — the distance the Sun has progressed, roughly one degree per year of life — to time significant developments.
Solar arc directions are a predictive technique that moves every point in your natal chart forward by the same amount — the arc the Sun has travelled by secondary progression, which works out to roughly one degree per year of life.
Because everything advances together, solar arc is prized for timing: when a directed point forms an exact aspect to a natal placement, it often coincides with a landmark year. It’s a technique from the serious end of predictive astrology, and — like progressions — one that most lightweight horoscope apps don’t attempt.
