Happy vernal equinox! The Sun moves North into the summer zone as it passes the origin of right ascension. How's that for a technical sounding sentence? What does it mean...? ah now that would be telling, but spring has sprung and for those of you with winter gloom the bright few days we've had recently have rather symbolically illustrated the astronomical seasonal shift.
For Right Ascension, the zero point is known as the First Point of Aries, which is the place in the sky where the Sun crosses the celestial equator at the March equinox.
