Explanation:
Recorded during 2024, this year-spanning series of images
reveals a pattern
in the seasonal drift of the Sun's daily motion
through planet Earth's sky.
Known to some as
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
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
half-way
between
the solstices, but not the figure-eight curve crossing point,
mark the 2024
equinoxes and the start of spring and fall.
Regional peaks and dormant volcano Mount Erciyes lie along the southern
horizon in the
2024
timelapse skyscape.
