When a planet forms no further aspect for the remainder of its time in a sign in which it is located (before changing to the next sign). Used mainly for the Moon in Horary Astrology, it is said by most modern astrologers that it indicates that nothing will come of the matter. It is a testimony that the horary chart is not radical. William Lilly, a prime authority on traditional astrology, holds that the Moon is not VoC if inside a moiety of an aspect, even if the aspected planet lies out of sign. He also holds that the Moon is never dangerously VoC in Taurus, Cancer, Sagittarius, or Pisces. Moreover he says that VoC does not necessarily signify that nothing will come of a matter, but that things "go hardly on" (i.e. "proceed with difficulty", unless the significators be strong, in which case there is no real problem with the Moon being VoC).
