On the spring equinox, in what part of the sky and what time of day does the full moon rise?
March 20th is the Spring Equinox for the northern hemisphere, the time of year when the sun is at zero degrees longitude and latitude on the ecliptic, and the hours of daylight and dark-of-night are of equal length.
On the equinoxes, the sun and moon pass each other in the sky at the intersection of the ecliptic with the celestial equator as they rise and set. (The ecliptic is the path followed by the planets against the backdrop of the constellations. The celestial equator is the projection of the Earth's equator onto the sky, an invisible line enabling us to determine whether a heavenly body hovers over our northern hemisphere or our southern hemisphere. These two invisible lines intersect at the equinoxes.)
