46th parallel south

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.
