Astrology Basics
Imum Coeli (IC)
The deepest point in your chart - your roots, home, and private self.
The Imum Coeli (IC, or "bottom of the sky") is the cusp of the 4th house, directly opposite the Midheaven. It represents your private life, family of origin, psychological foundations, and what you need to feel at home. While the MC is your public face, the IC is your private sanctuary.
Example
A Cancer IC suggests deep ties to family, a need for emotional security at home, and possibly living near water.
