happy vernal equinox!

its nice to live again where the change of seasons somewhat coincide with the astronomical definitions! flowers are beginning to poke out of the ground and bloom! yeah springtime! and i hope all you southern hemispherians are ready for the summer heat to subside!

today is the vernal equinox. the hours of daylight and darkness are very nearly equal. why? the earth spins around once a day on an axis that is not perpendicular to the plane in which the earth revolves around the sun. if it were perpendicular, we would not have the seasons we feel. right now, the earth's spin axis is not facing towards or away from the sun.... it's exactly in the middle of those two extremes!

and no, it is NOT true that you can only stand an egg on its end during the vernal equinox!!! why does that idea even make sense to some people?

bienvenida la primavera!

Happy Vernal Equinox to you too, but if you have deal with geostationary satellites, near the Equinoxes we have to deal with those bothersome eclipses - better have your batteries charged!
