Sextile, Hexagon (60°).

A favoring aspect, involving planets in congenial signs of the same polarity (q.v.). Alan Leo says of the Sextile aspect: that it partakes of the nature of Moon and Neptune; that it is more combining than any other aspect, and is often more potent and favorable than the trine; that its color largely depends on the nature of the planets involved, and of the Signs they occupy; and that while the trine may be said to denote negative goodness such as a reward for past deeds, the sextile denotes positive good in that it generates the activity that produces change and thus possesses greater potentiality for the future.
