Halley Research Station Analemma

Due to Earth's tilted axis and slightly elliptical orbit, the Sun is never seen in the same position at noon in Halley Research Station. 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 Halley Research Station.

Over the year, the 12:00 Sun ranges from 9.7° below the horizon (around Jun 21) to 36.9° above it (around Dec 24) in Halley Research Station. The smaller loop hangs at the bottom, the signature of a Southern Hemisphere analemma. For about 111 days around midwinter the whole figure sinks below the horizon — the Sun does not rise at noon at all. Notice the whole figure leans west of the meridian: over Halley Research Station the Sun reaches its highest point between 10:25 and 10:56 depending on the time of year, but always before 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.
