The Fall Autumnal Equinox

Yesterday, Sept 22, 2010 was the Fall Equinox.

So what is the Fall Autumnal Equinox and why is it important?

Well, for one thing, the Fall Autumnal Equinox is that special day at the end of summer and the beginning of fall when the sun at the equator rises in the due East and sets in the  due West.

Thus, both the day and the night are about 12 hours long. The reason why they are not exactly 12 hours each is explained in the article below.

But, more significantly to most of us, the days start getting shorter and shorter and shorter as each day passes and the nights get longer and longer and longer ....

Until we come to the Winter Solstice when the shortest day of the year occurs.

But that is then and this is now.

And yesterday was the Fall Autumnal Equinox, if you were paying attention, you would have noticed that there we had about 12 hours of day and about 12 hours of night.

Well, I didn’t pay attention to that either. But it happened.

Anyway, to read more about the Equinoxes and see a really interesting 2 min 38 second video from National Geographic, which was posted for the 2009 equinox  but same thoughts apply every year including 2010, HERE’S THE LINK.
