21. Approximately, such a route is a segment of a great circle, such as a line of longitude or the equator. 22. On it lay off ticks westwards starting at the 118th lines of longitude ( 5th and 6th DLS meridians ). 23. The control center predicted that the 180-foot-high balloon would reach the finish line of longitude 9 degrees west around 1000 GMT. 24. The control center predicted that the 180-foot-high balloon would reach the finish line of longitude 9 degrees west around 1030 GMT. 25. Palmer Land borders Ellsworth Land along the 80?W line of longitude , and is bounded in the south by Carlson Inlet. 26. The control center predicted that the 180-foot-high balloon would reach the finish line of longitude 9 degrees west around 0930 GMT. 27. The length of polar lines are half that of the equator, and lines of longitude are semiellipses, or portions of ellipses. 28. As with other segments of Antarctica, it is defined by two lines of longitude , 142?2'E and 153?5'E, and by the 60�S parallel. 29. The length of the polar lines is half that of the equator, and lines of longitude are semiellipses, or portions of ellipses. 30. I've been looking : Category : Lines of longitude and there definitely needs to be a large number of changes to the sorts there.
