Juan Carlos I Base Analemma

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

Over the year, the 12:00 Sun swings between just 3° above the horizon (around Jun 21) and 49.5° (around Dec 18) in Juan Carlos I Base. The smaller loop hangs at the bottom, the signature of a Southern Hemisphere analemma. Notice the whole figure leans east of the meridian: over Juan Carlos I Base the Sun reaches its highest point between 12:45 and 13:15 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.
