High Noon Analemma Over Azerbaijan
Explanation: Is the Sun always straight up at noontime? No. For example, the Sun never appears directly overhead from locations well north or south of the Earth's equator. Conversely, there is always a place on Earth where the Sun will appear at zenith at noon -- for example on the equator during an equinox . Turning the problem around, however, as in finding where the Sun actually appears to be at high noon , is as easy as waiting for midday, pointing your camera up, and taking a picture. If you do this often enough , you find that as the days march by, the Sun slowly traces out a figure eight on the sky. Pictured above is one such high noon analemma -- a series of pictures always taken at exactly noontime over the course of a year. The above fisheye image , accumulated mostly during 2012, also shows some buildings and trees of Baku , Azerbaijan around the edges.
