Today is the first official day of Fall, which began with the autumnal equinox at 11:09 p.m. EDT last evening. It was also a special equinox since the full moon occurred last night creating a true “Harvest Moon” called such because it is when the full moon occurs closest to the autumnal equinox – it happened this year just about as close as it could get, within hours of each other. The equinox is one of the two times in the year that the sun rises exactly due east and sets exactly due west. While the actual day of the equinox can vary from year to year, it is interesting to note that it will never occur in my lifetime on my birthday. The last time it occurred on September 24th was in 1931 and the next time will be in 2303.
