Analemma Rising Sun with Venus transit


An analemma is shaped curve "8" you get to mark the position of the Sun at the same time every day of the year Earth. In this case, the 17 photographs taken at 02:31 TU between 2 April and 16 September are half the analemma curve. The photos look east, toward the rising sun and the Caspian Sea, from the harbor promenade of Baku in Azerbaijan.

Dates mentioned, covering roughly the period between the equinoxes of 2012 (pictured at right), ie, between March 20 and September 22, match the shots in which the Sun was closer the horizon. The solstice in the northern hemisphere summer, occurred on June 20, corresponds to the upper left of the "8" when the sun was at its maximum declination north.
