Variations of the diurnal arc of the Sun during the zodiacal year: video
by Julien Rouger
English translation by Julien Rouger

Variations of sunrise, Sun’s culmination and sunset throughout the zodiacal year. The Sun’s yearly apparent trajectory (ecliptic) is displayed. Simulation created with the Stellarium freeware. Simulated observation from the 45th parallel north, located halfway between the Earth’s equator and the North Pole. This corresponds to the following regions: southern France, northern Italy, Croatia, Serbia, Romania, Kazakhstan, Mongolia, southern Russia, northern China, northern Japan, northern United States, southern Canada.

From March equinox to December solstice

March equinox

▶ the Sun leaves the ecliptic sector of Pisces and enters Aries. It is then vertical to the Earth’s equator.

▶ everywhere on Earth, the Sun rises in the east and sets in the west, while the lengths of days and nights are practically equal (12 hours each).

▶ throughout the northern hemisphere it is the time of the year when the days increase the fastest while the nights decrease the fastest. For six months until September equinox, the days will be longer than the nights.

▶ seen from the 45th parallel north, when facing due south in the early afternoon, the Sun culminates at about 45° above the horizon.

June solstice

▶ the Sun leaves the ecliptic sector of Gemini and enters Cancer. It is then vertical to the Tropic of Cancer (at about 23° north latitude).

▶ throughout the northern hemisphere it is the longest day and the shortest night of the year. The Sun rises in the northeast and sets in the northwest. For six months until December solstice, the days will get shorter and shorter while the nights will get longer and longer.

▶ seen from the 45th parallel north, the visible trajectory of the Sun lasts about 15 hours. When facing due south in the early afternoon, the Sun culminates at about 68° above the horizon.

September equinox

▶ the Sun leaves the ecliptic sector of Virgo and enters Libra. It is then vertical to the Earth’s equator.

▶ everywhere on Earth, the Sun rises in the east and sets in the west, while the lengths of days and nights are practically equal (12 hours each).

▶ throughout the northern hemisphere it is the time of the year when the days decrease the fastest while the nights increase the fastest. For six months until March equinox, the days will be shorter than the nights.

▶ seen from the 45th parallel north, when facing due south in the early afternoon, the Sun culminates at about 45° above the horizon.

December solstice

▶ the Sun leaves the ecliptic sector of Sagittarius and enters Capricorn. It is then vertical to the Tropic of Capricorn (at about 23° south latitude).

▶ throughout the northern hemisphere it is the shortest day and the longest night of the year. The Sun rises in the southeast and sets in the southwest. For six months until June solstice, the days will get longer and longer while the nights will get shorter and shorter.

▶ seen from the 45th parallel north, the visible trajectory of the Sun lasts about 9 hours. When facing due south in the early afternoon, the Sun culminates at about 22° above the horizon.
