Planets seperating.

How do i know if a planet is seperating/about to seperate or has separated ?

Going by a chart on astro, then the table underneath with the planets interactions with each other, are the planets that have seperated got the S next to them ?

Its okay ive got this now....

Applying aspects are (A) - which are the best, as they show whats about to happen.

Separating aspects (S) - Shows what's already happened.

That's it
