Happy Vernal Equinox!

Behold the intersection of the ecliptic and the celestial equator,  when the earth's axis was perpendicular to the sun's rays, at 23:21 Greenwich Mean Time on March 20, 2011 -- almost five hours before this post went up.  Spring has sprung!

  1. I pointed out to my neighbors in Minneapolis that the equinox may be the beginning of astronomical spring, but it ain't so in Minnesota, where spring comes (if at all) in May or June. (tongue now removed from cheek)
