Autumn Has Arrived

Today is the first day of fall, the autumnal equinox, where the sun is directly above the equator and the length of day and night are nearly equal. The autumnal equinox occurred early this morning at 3:09 UTC, Coordinated Universal Time. But here in America, the equinox occurred last night, at 11:09 on the East Coast.
