Sunrise 7:11: Day after spring


The female Dawn Jogger heard the KFOG newscaster declare today the first day of spring. The calendar date of March 21 would be correct - if this was the UK instead of the US.
As Natalie Angier (one of the DJs all-time favorite science writers) points out yesterday in an article in the New York Times, "Coordinated Universal Time is what used to be called Greenwich Mean Time, but the new name doesn’t make it any more universal than it ever was, and it remains a time zone centered in Britain. For those of us in the United States, the vernal equinox arrives while it is still the evening of March 20." She goes on to give a wonderfully poetic account of the earth's tilt and seasonality. Even a half day late, it was a pretty morning atop the Dish, though the sun didn't make its first appearance of spring until the female DJ was well down the Alpine Rd. side. The female DJ admits to being thrilled that she's not along in being an observer of the sun's tilt; thank you, Natalie...
