Calculate the solar arc at which a directed planet will aspect a natal point.
Parameters
natalDirecting: number
Natal longitude of body being directed
natalReceiving: number
Natal longitude of body receiving the aspect
aspectAngle: number
Aspect angle (0, 60, 90, 120, 180)
Returns number[]
Solar arc at which aspect is exact
Example
// When will directed Mars (natal 100°) square natal Sun (natal 50°)? // Square = 90°, so Mars at 140° squares Sun at 50° // Arc needed = 140 - 100 = 40° constarc = solarArcForAspect(100, 50, 90); console.log(arc); // 40°
Calculate the solar arc at which a directed planet will aspect a natal point.
