Quincunx. An aspect of 150°, creating stress, unhappiness and sorrow. The aspect has a 6th or 8th house effect, depending on whether the swifter planet is applying or separating from the opposition to the slower. Technically this is not a proper aspect in the traditional sense, as a planet is unable to "see" another in this relationship. Considered particularly unfortunate by the ancients, this aspect is not thought unduly malefic by many modern astrologers, but it is to be ignored at one's peril.
