Separating
An aspect is separating when the two planets have already passed the exact angle and are drawing apart. A separating aspect describes something that has happened, not something coming.
The fuller picture
When two planets have gone past exactness they begin to separate, and the orb starts to grow again. For a separating aspect the orb is the distance travelled since the contact was exact, which makes it a rough measure of how long ago the thing happened rather than how long until it does. The tradition reads that plainly: applying aspects are events in the future, separating aspects events in the past.
This is the distinction worth the page, because a separating aspect is not a weakened applying one. It isn't the same event at lower volume — it's a different tense. A trine two degrees past exact isn't a bit of good fortune on its way; it's good fortune already spent. Reading a separating trine as a mild yes is one of the commonest ways a beginner talks themselves into an answer the chart never gave.
The practice this glossary follows takes the strictest available line and says so against Lilly, who happily read a separating square as testimony: within this approach, only applying aspects are interpreted, because a separating aspect represents action already taken. What the separation is good for is description. On one worked chart a separating square is read as a plain statement of past fact about the querent's life — an expensive trip five months earlier — rather than as evidence towards the verdict. That's the honest use of it: the chart is telling you where this person has been, which is often exactly what they need to hear, and it isn't an argument about what happens next.
Two places a separation does real work, though. The first is translation of light, where a faster planet has to have come off one significator before applying to the other — that prior separation is the entire difference between a go-between and an interloper who's simply beaten everyone to it. The second is a question about the past. Where someone asks whether a thing has already happened, a completed contact between the two significators is the affirmative answer, graded by how exact it was, and a separating square still means it happened — badly, or leaving something unfinished. Valence isn't occurrence. A hard aspect in the past records a meeting that went wrong, never the absence of a meeting.
Our own position sits between the two. We keep separating aspects visible and never let one carry a yes on a question about the future: where the two rulers make no applying aspect, a recent separation between them is reported as context — the matter has lately been in contact, retrace recent steps — with more weight the tighter it is, and none at all beyond ten degrees.
In your chart
Separating aspects are drawn as dashed lines on the wheel, and the aspect dossier tones a separating contact quietly whatever its nature, because a past benefic is no promise and a past malefic no threat. The Moon's last completed aspect is reported on its own as the most recent significant event behind the question. On a question about something that has already happened, the engine switches which tense it judges from: a completed contact between the two rulers becomes the path to yes, marked as past so it can't be confused with an applying one, and graded partile inside a degree, close inside three, wide beyond that.
