Explanation:
Recorded from 2024 March 10, to 2025 March 1, this
composited 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 on the indicated dates
only at 18:38 UTC from the exact same
location south of Stephenville,
Texas.
The Sun's position on the 2024
solstice dates of June 20 and
December 21 would be at the top and bottom of the curve
and correspond to the astronomical
beginning of summer and winter in the north.
Points that lie along the curve
half-way
between
the solstices would mark the equinoxes.
The 2024 equinox on September 22,
and in 2025 the equinox on March 20 (today)
are the start of northern fall and spring.
And since one of the exposures was made on 2024 April 8 from the Stephenville
location at 18:38:40 UTC, this analemma project
also reveals the solar corona in planet Earth's sky during a
total
solar eclipse.
