Big Bend National Park, TX Analemma

Due to Earth's tilted axis and slightly elliptical orbit, the Sun is never seen in the same position at noon in Big Bend National Park. Throughout the year, it slowly traces this figure-eight:

Move along the curve to read the Sun's altitude and azimuth for any day of the year in Big Bend National Park.

Over the year, the 12:00 Sun swings between just 35.8° above the horizon (around Dec 24) and 76.7° (around Jun 9) in Big Bend National Park. The smaller loop sits at the top, the signature of a Northern Hemisphere analemma. Notice the whole figure leans east of the meridian: over Big Bend National Park the Sun reaches its highest point between 12:36 and 13:07 depending on the time of year, but never at 12:00.

Why does the figure look wider here than in the sky view above?

Both draw the same data, but with different conventions. The sky view uses the same scale on both axes, so it shows the analemma with its true proportions, as a camera would capture it: about 47° tall and only a few degrees wide. This chart, like most technical analemma diagrams, stretches each axis independently to fill the plot, expanding the narrow azimuth range several times so its day-to-day variation can actually be read. Also, azimuth is not sky distance: near the zenith, one degree of azimuth spans much less than one degree across the sky, which further widens the figure in this representation.
