Arrecifes Analemma

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

June solstice · Jun 21 · Sun altitude: 30.6°December solstice · Dec 21 · Sun altitude: 73.4°March equinox · Mar 20 · Sun altitude: 52.4°September equinox · Sep 22 · Sun altitude: 53.6°Today · Oct 12 · Sun altitude: 61.4°

Move along the curve to read the Sun's altitude and azimuth for any day of the year in Arrecifes.

Over the year, the 12:00 Sun swings between just 30.6° above the horizon (around Jun 24) and 73.9° (around Dec 9) in Arrecifes. The smaller loop hangs at the bottom, the signature of a Southern Hemisphere analemma. Notice the whole figure leans east of the meridian: over Arrecifes the Sun reaches its highest point between 12:43 and 13:14 depending on the time of year, but never at 12:00.

The technical chart below plots one dot per day, labels the first day of each month, marks the solstices, equinoxes, perihelion and aphelion, and draws the noon altitude of the equinoxes (90° minus your latitude) together with its ±23.4° seasonal limits.

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.
