Move along the curve to read the Sun's altitude and azimuth for any day of the year in Castelo do Piauí.
Over the year, the 12:00 Sun swings between just 61.1° above the horizon (around Jun 21) and 89.2° (around Mar 5) in Castelo do Piauí. Sitting almost under the Sun's yearly path, Castelo do Piauí sees the analemma lying nearly flat overhead, with the Sun passing practically through the zenith twice a year.
Detailed Analemma Chart
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.
