An astrology term meaning the point on the Eastern horizon at the time of birth, or the sign on the cusp of the first house in a horoscope. Tis is the representative of the sun as it appears in natal charts. What it affects is a persons outward personality, what they reflect and project to others. Though this may seem confusing, it is not to be mistaken for the actual sun sign. Also one of the three aspects that are considered most important in finding out what a person is made of astrologically speaking.
