This moment -- yep, right now-- marks the midpoint between the summer and winter solstices: the autumn equinox. Among other things, today the sun will rise due east and set due west; and there will be equal hous of daylight and night. From now until the winter solstice on Dec. 21, the days will continue to shorten, and the sun will cross ever lower (and more southern) in the sky. It's a great time of year to work outdoors, and the sharp contrast between daytime and nighttime temps sets the stage for brilliant autumn leaves.
