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.
