Posted on 09/22/2012 9:16:55 PM PDT by SunkenCiv
Explanation: Yesterday was an equinox, a date when day and night are equal. Today, and every day until the next equinox, the night will be longer than the day in Earth's northern hemisphere, and the day will be longer than the night in Earth's southern hemisphere. An equinox occurs midway between the two solstices, when the days and nights are the least equal. The picture is a composite of hourly images taken of the Sun above Bursa, Turkey on key days from solstice to equinox to solstice. The bottom Sun band was taken during the winter solstice in 2007 December, when the Sun could not rise very high in the sky nor stay above the horizon very long. This lack of Sun caused winter. The top Sun band was taken during the summer solstice in 2008 June, when the Sun rose highest in the sky and stayed above the horizon for more than 12 hours. This abundance of Sun caused summer. The middle band was taken during the Vernal Equinox in 2008 March, but it is the same sun band that Earthlings saw yesterday, the day of the Autumnal Equinox.

Wikipedia says Bursa, Turkey is 40 degrees 11 minutes North.
There is an SUV called Equinox, a sports car called Solstice.
What kind of car would be called ‘Analemma’?.......
That looks completely awesome.
A planet with too many suns!
Don’t forget about the up-and-coming supercars comprising Aphelion, Syzygy, and of course, the inestimable Inferior Conjunction.
Dark at 730 PM. Ugh.
Which happens to be about that of Boulder, CO (and nearby towns).
Gotta have a really, really high sunblock number.
Tne equinox, when the dark area would have been most square, was at 14:49 UTC yesterday.
I have always prayed for world peas. Now, my prayers have been answered.
Day and night may be officially equal at the equinox, but in fact there is a bit more than 12 hours between sunrise and sunset for a few days after the fall equinox (and for a few days before the spring equinox) because the atmosphere makes the sun appear to be still above the horizon for a few minutes after it has set and before it rises.
A "Demo Derby" figure eight racer?
