Year distribution of sunrise and sunset times in Marambio Base, Antarctic Peninsula - 2026
The following graph shows sunrise and sunset times in Marambio Base, Antarctic Peninsula for every day of the year.
Daylight Dawn & dusk (civil twilight) Night Solar noon
Earliest and latest sunrise and sunset in Marambio Base
In Marambio Base, the earliest sunrise of 2026 is on December 19 at 2:07 am, while the latest sunrise is on June 22 at 10:46 am. The earliest sunset is on June 19 at 2:49 pm, and the latest sunset is on December 23 at 11:22 pm.
Marambio Base gets 17h 10m more daylight on the longest day than on the shortest one (21h 14m versus 4h 03m). Averaged over the whole year, a day lasts 12h 15m.
Marambio Base Analemma
Due to Earth's tilted axis and slightly elliptical orbit, the Sun is never seen in the same position at noon in Marambio Base. 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 Marambio Base.
Over the year, the 12:00 Sun swings between just 1.8° above the horizon (around Jun 21) and 48.5° (around Dec 18) in Marambio 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 Marambio Base the Sun reaches its highest point between 12:30 and 13:00 depending on the time of year, but never at 12:00.
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.
