September 6, 2012 - End of Summer

We are officially at the end of Summer - as far as the school calendar goes. Meteorologically, the average daytime highs have been heading downward since July when it hits its peak. Average nighttime lows have also been heading the same direction. Which to me, sort of indicates the departure of Summer. Then too, the days have shortened noticeably since June when we had our longest day - 15 hours, 23 minutes of daylight. Right now we're hanging right below 13 hours of daylight. Summer won't end astronomically until September 22nd. The 22nd is the autumnal equinox with the sun rising at 6:45 and setting at 18:54 (6:54) - but as you can see, it isn't exactly even as far as hours of night and day are concerned. There's a nine minute difference which actually resolves on the 25th when there are 12 hours of daylight and 12 hours of night - at least at this longitude and latitude. This is the explanation for this discrepancy from Infoplease "In the language of science, an equinox is either of two points on the celestial sphere where the ecliptic and the celestial equator intersect. For the rest of us, it's one of two times a year when the Sun crosses the equator and the day and night are of approximately equal length. At the autumnal equinox (September 22, 2012, 10:49 A.M.), the Sun appears to cross the celestial equator, from north to south; this marks the beginning of autumn in the Northern Hemisphere." Anyway you look at it, Fall will be arriving soon. As far as I'm concerned, once the regular football season starts, Fall has arrived. And speaking of Fall, and arriving. The Fall books have started to arrive and there is a list of new title further down this page for you to peruse. Enjoy!
