Alas, the end of summer

Today the sun will move from the Northern Hemisphere to the Southern Hemisphere.  It will pass overhead everywhere along the Earth's equator on the date, and the sun will rise exactly in the east and set exactly in the west.  Day and night will be roughly equal length.  Equinox is derived from the Latin for "equal night".
