When an applying aspect is 'refrained' from reaching perfection. Often when one of the significators turns retrograde preventing perfection of the aspect. Refranation in a horary chart indicates that the matter questioned about is blocked from a conclusion. Let's say however that Mercury having separated from a conjunction with Venus turns retrograde and procedes to meet Venus again; there would be no refranation here, as the aspect does complete. In general, refranation does not occur, in spite of retrograde motion, when the two planets eventually complete an aspect within the sign in which they are originally place; such a condition would signify delay in the resolution of the question. The rules of refranation were set down before astrologers worked with Uranus, Neptune and Pluto. Modern horary astrologers work with these planets in relation to the faster moving bodies and as topical significators. They generally do not consider the aspects these three planets may form among themselves. Aspect time scales, now a popular feature on astrology computer programs, simplify spotting refranation in a horary chart.
