46th parallel south (interactive map)

In Argentina, the 46th parallel south defines the border between Chubut Province and Santa Cruz Province.

The 46th parallel south is a circle of latitude that is 46 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, the Indian Ocean, Australasia, the Pacific Ocean and South America.

At this latitude the sun is visible for 15 hours, 45 minutes during the December solstice and 8 hours, 38 minutes during the June solstice. ^[1] This holds true regardless of longitude.

The largest city south of the 46th parallel is Punta Arenas.

49th parallel south (interactive map)

The 49th parallel south is a circle of latitude that is 49 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, the Indian Ocean, the Pacific Ocean and South America.

At this latitude the sun is visible for 16 hours, 13 minutes during the December solstice and 8 hours, 14 minutes during the June solstice. ^[4]

This latitude also roughly corresponds to the minimum latitude in which astronomical twilight can last all night near the summer solstice. All-night astronomical twilight lasts about from December 11 to January 1 of the following year. At midnight on the summer solstice, the altitude of the sun is about −17.56°.

50th parallel south (interactive map)

The 50th parallel south is a circle of latitude that is 50 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, the Indian Ocean, the Pacific Ocean and South America.

At this latitude the sun is visible for 16 hours, 23 minutes during the December solstice and 8 hours, 4 minutes during the June solstice. ^[5] On December 21, the sun is at 63.44 degrees in the sky and on June 21, the sun is at 16.56 degrees in the sky. During the summer solstice, nighttime does not get beyond astronomical twilight, a condition which lasts throughout the month of December. It is possible to view both astronomical dawn and dusk every day of the month of November.

The maximum altitude of the Sun is > 25.00º in April and > 18.00º in May.

The 50th parallel is the northerly boundary of the Dependencies of the Falkland Islands, the southerly boundary being the 60th parallel south. ^[6]
