Year distribution of sunrise and sunset times in Rothera Research Station, Antarctic Peninsula - 2026
The following graph shows sunrise and sunset times in Rothera Research Station, Antarctic Peninsula for every day of the year.
Daylight Dawn & dusk (civil twilight) Night Solar noon
Earliest and latest sunrise and sunset in Rothera Research Station
In Rothera Research Station, the earliest sunrise of 2026 is on November 29 at 1:46 am, while the latest sunrise is on June 28 at 1:28 pm. The earliest sunset is on June 28 at 1:43 pm, and the latest sunset is on January 12 at 1:16 am (after midnight).
Rothera Research Station gets 24h 00m more daylight on the longest day than on the shortest one (24h 00m versus 0h 00m). Averaged over the whole year, a day lasts 12h 18m.
Rothera 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 Rothera 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 Rothera Research Station.
Over the year, the 12:00 Sun ranges from 2.7° below the horizon (around Jun 21) to 43.7° above it (around Dec 18) in Rothera Research Station. The smaller loop hangs at the bottom, the signature of a Southern Hemisphere analemma. For about 57 days around midwinter the whole figure sinks below the horizon — the Sun does not rise at noon at all. Notice the whole figure leans east of the meridian: over Rothera Research Station the Sun reaches its highest point between 13:16 and 13:46 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.
