Astronomy Picture of the Day -- Equinox: The Sun from Solstice to Solstice
NASA ^ | September 23, 2012 | (see photo credit)

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.

There is an SUV called Equinox, a sports car called Solstice.

What kind of car would be called ‘Analemma’?.......

Don’t forget about the up-and-coming supercars comprising Aphelion, Syzygy, and of course, the inestimable Inferior Conjunction.

You must be close to the Pittsburgh area, I live here too so I've noticed it as well.

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.
