Well we made it to Spring and although it doesn’t really feel like it, according the calendar it has arrived. So for our primaveral activity we seem to be hauling a boat.

Simultaneously, it happens on the imaginary dome of our sky. The imaginary celestial equator is a great circle dividing the sky into Northern and Southern Hemispheres. The celestial equator wraps the sky directly above Earth’s equator. At the equinox, the sun crosses the celestial equator, to enter the sky’s northern hemisphere. On the Vernal Equinox day and night are exactly 12 hours each. Read more at the Earth Sky website.
