🧮 Calculation
Definition: Intersection of the ecliptic with the local meridian, above the horizon (Medium Coeli).
- λ_MC = atan2( sin θ , cos θ · cos ε )
- θ = RAMC (local apparent sidereal time × 15°), ε = true obliquity of the ecliptic (≈ 23.436° in 2026), φ = geographic latitude.
Usage note: Cusp of the 10th house in quadrant systems. In equal and whole-sign houses the MC floats and can fall in the 9th–11th houses.
