The 63rd parallel north is a circle of latitude that is 63 degrees north of the Earth's equatorial plane. It crosses the Atlantic Ocean, Europe, Asia and North America.
At this latitude the sun is visible for 20 hours, 19 minutes during the summer solstice and 4 hours, 43 minutes during the winter solstice. If the latitude in the northern hemisphere is 63º26' or smaller, it is possible to view both astronomical dawn and dusk every day of the month of September.
Starting at the Prime Meridian and heading eastwards, the parallel 63° north passes through:
The 45th parallel south is a circle of latitude that is 45° south of the Earth's equator.

The 70th parallel north is a circle of latitude that is 70 degrees north of the Earth's equatorial plane, in the Arctic. It crosses the Atlantic Ocean, Europe, Asia and North America, and passes through some of the southern seas of the Arctic Ocean.
The 30th parallel south is a circle of latitude that is 30 degrees south of the Earth's equator. It stands one-third of the way between the equator and the South Pole and crosses Africa, the Indian Ocean, Australia, the Pacific Ocean, South America and the Atlantic Ocean.
