South Geomagnetic Pole
The Earth's geomagnetic field can be approximated by a tilted dipole (like a bar magnet) placed at the center of the Earth. The South Geomagnetic Pole is the point where the axis of this best-fitting tilted dipole intersects the Earth's surface in the southern hemisphere. As of 2005 it was calculated to be located at 79°44′S 108°13′E / 79.74°S 108.22°E / -79.74; 108.22, near the Vostok Station. Because the field is not an exact dipole, the South Geomagnetic Pole does not coincide with the South Magnetic Pole. Furthermore, the South Geomagnetic Pole is wandering for the same reason its northern magnetic counterpart wanders.

Famous quotes containing the words south and/or pole:
“I don’t have any doubts that there will be a place for progressive white people in this country in the future. I think the paranoia common among white people is very unfounded. I have always organized my life so that I could focus on political work. That’s all I want to do, and that’s all that makes me happy.”
—Hettie V., South African white anti-apartheid activist and feminist. As quoted in Lives of Courage, ch. 21, by Diana E. H. Russell (1989)
“I wouldn’t take the Pope too seriously. He’s a Pole first, a pope second, and maybe a Christian third.”
