This month’s moon arrives alongside a total solar eclipse, a pairing astrologers say could mark a major turning point. Astronomically, a solar eclipse occurs when the Moon passes between the Earth and the Sun, temporarily blocking the Sun’s light. This eclipse also marks the beginning of an 18-month Leo–Aquarius eclipse cycle, so the themes that start emerging now aren’t necessarily going to play out overnight. “This eclipse also begins an 18-month Leo–Aquarius eclipse cycle, so pay attention to what starts unfolding in your Leo house now,” Weber says. Your Leo house refers to the area of your birth chart where Leo falls.
