This is the second Full Moon in Aquarius this year (the first occurred last month on July 23, 2021). This lunation occurs late in the sign of Aquarius, right near the cusp of Pisces.
A Full Moon occurs when the Sun in Leo forms an opposition to the Moon in Aquarius. The Full Moon is a time of culmination and the promise of fulfillment of that which was started at the New Moon. It is an emotional time – a time of romance, fertilization, and relationships.
As the second Full Moon in Aquarius this year and occurring at the tail-end of the sign, this is about final events that awaken our feelings and that might spur us into action.
