Mercury-Uranus minor aspects
From AstrologyNotes
The following aspect interpretations apply only to natal or birth charts. Please see Synastry aspects for comparison charts, and Interpreting transits for transit aspects.
Semisextile
This aspect is very subtle, giving the owner of it spontaneous insights or outbursts of creative genius. What seemed like an educated guess on a test, turns out to be the right answer. The well timed joke that makes a room erupt with laughter. A stinging come-back when cut down. Being able to fix a problem, that others had given up on, without deliberation. The aspect is not reliable as a conjunction, sextile, or trine. If Mercury and Uranus have other supporting aspects, or they are significant planets within the chart, the traits will manifest more often.
Semisquare/Sesquiquadrate
Quintile/Biquintile
