"First day of fall brings autumnal equinox Wednesday"

            In the short but sweet article “First day of fall brings autumnal equinox Wednesday” by Jeanine Junell it explains how that on this past Wednesday (September 22, 2010) there was a very rare equinox going on right above us. At the exact moment of 9:09pm (MDL time) the center of the Sun was directly over the Earth’s equator. What is the significance of this? Well because of the Earth’s tilted axis this gave us almost exactly 12 hours of night and 12 hours of day. This still may not sound very important, but the reason it is so rare is because it happened while there was a full moon. Also called the harvest moon. This event last occurred in 1991 and won’t be coming back until 2029.

            I chose this article because I really am interested by the changing seasons. Along with our solar system and the orbit patterns that go on in it. The thing the stuck out to me the most about this article was the fact that it happens barely ever, but it still isn’t recognized as a rare event as most people didn’t even know it was going on yesterday.
