The March Equinox marks the moment when the Sun crosses the Celestial Equator going from South to North; it signals the beginning of Spring in the Northern Hemisphere and Autumn in the Southern One. The tropical 0 Aries i.e. the ’Vernal Point’ is in the constellational Pisces at present, below the ’Western Fish’, between the stars called omega and iota Piscium.
Happy Equinox, Everyone!
