FIRST DAY OF NORTHERN AUTUMN: The seasons are changing. Today, Sept. 22nd at 10:49 a.m. EDT, the sun crosses the celestial equator heading north. This marks the beginning of autumn in the northern hemisphere and spring in the southern hemisphere. At this time of year, day and night are of nearly equal length, hence the name "equinox" (equal night).http://www.spaceweather.com ... http://sohowww.nascom.nasa.gov
