What is the Ascendant in Astrology
Your Rising Sign, otherwise known as an Ascendant, is the Zodiac Sign that was rising on the eastern horizon at the moment you were born. It can be abbreviated on a birth chart as ASC or AS. When you know the time you were born, your Ascendant Sign can be calculated to the exact degree.
It is believed that if the Ascendant falls closer to the beginning of the Sign, the stronger the effects will be felt in the individual. This is also held to be true if the Sun is in a weak position in the birth chart (such as if the individual was born at night). It is also thought to be weaker when the individual is born towards the end of the Sign's Ascendancy, just before the next Sign appears.
Because the Ascendant Sign is specific to the time and place of the individual birth, it represents the environment and conditioning a person may be influenced by during their childhood and is considered as important and significant as the Sun and Moon Signs, because all other aspects on the chart are filtered through this Sign.
The Ascendant is said to be the mask one wears in public. It is the first impression we make when we meet new people. Often, if you are confused at how others have described you, it is because they are describing this aspect of your personality. The Ascendant takes part in your appearance and personality, going as far as influencing physical characteristics sometimes. The Sign becomes expressed in your image, style and mannerisms. It is also expressed in how you act. Some astrologists theorize that the Sign becomes weaker after a person reaches 30 years of age, as their confidence grows in who they are.
