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.
