As is always the case with a full moon, the moon sits across the sky from the sun in the opposite side of the zodiac, staring each other down, and therefore shining the full light of the sun onto the reflective moon. The moon rules Cancer, so it doesn’t fare well in the opposite sign, Capricorn (it’s in its fall here, a debilitated placement). Capricorn is rather dry and harsh for the watery moon. Ruled by Saturn, planet of boundaries, Capricorn is known for rational thinking, rules and structure—quite different from oceanic Cancer.
