Quintile. A group of aspects, introduced by Kepler, based on a division of one-fifth of the
circle. They have had limited adoption, and their value is chiefly in directions. They are:
Bi-Quintile........................ 144°
Tridecile.......................... 108°
Quintile (one-fifth of 360°)....... 72°
Decile or Semi-Quintile............ 36°
Quindecile......................... 24°
Semi-Decile, or Vigintile.......... 18°
Combust. Said of a planet closer than 5° to the Sun. It introduces factors that considerably
alter the interpretation of the conjunction.
Cazimi. A planet within 0°17' of the Sun's longitude is said to be "in the heart of the Sun" - or

Abscission, or Frustration. When a planet is simultaneously forming an aspect to two other
planets, the one that culminates first may produce an abscission of light that will frustrate the
