72nd parallel south

This is the parallel where twilight/nighttime boundary on the equinoxes.

This is also the lowest parallel that golden hour occurs even at midnight sun, because the Sun is less than 6°00'00" above the horizon. Midnight Sun without golden hour occurs at latitudes greater than 72°33'38.58804", i.e., about 666.8 km (414.3 mi) south of the Antarctic Circle in the case of the December Solstice.
