   Explanation: Recorded during 2024, this year-spanning series of images
   [5]reveals a pattern in the seasonal drift of the Sun's daily motion
   through planet Earth's sky. Known to some as [6]an analemma, the
   figure-eight curve was captured in exposures taken only at 1pm local
   time on clear days from Kayseri, Turkiye. Of course the Sun's position
   on the 2024 [7]solstice dates was at the top and bottom of the curve.
   They correspond to the astronomical beginning of summer and winter in
   the north. The points along the curve [8]half-way between the
   solstices, but not the figure-eight curve crossing point, mark the 2024
   [9]equinoxes and the start of spring and fall. Regional peaks and
   dormant volcano Mount Erciyes lie along the southern horizon in the
   [10]2024 timelapse skyscape.
