Sesquisquare

A sesquisquare (also called a sesquiquadrate) forms when two planets are approximately 135 degrees apart -- literally "a square and a half." If a square is a full-body rash you can't ignore, and a semisquare is a tiny mosquito bite, the sesquisquare is an itchy tag on the back of your shirt: not an emergency, but persistently annoying, and if you don't deal with it, you'll be irritable all day. This aspect creates a more agitated version of square-family friction, a restless, building tension that demands resolution. It often manifests through external events that shake you out of complacency and force you to finally address what you've been avoiding. In the aspect cycle, the sesquisquare comes late -- it's the waning-phase crisis, where something that worked earlier now needs to be released or reformed. Traditional astrologers called it the trioctile. You'll often see it active in transit during those weeks when minor annoyances pile up until you finally snap and change something.
