UTM zones are numbered 1 through 60, starting at the international date line, longitude 180Â°, and proceeding east. Zone 1 extends from 180Â° W to 174Â° W and is centered on 177Â° W. Each zone is divided into horizontal bands spanning 8 degrees of latitude.
Since the Earth's axis is tilted 23.5 degrees, then on this particular day, the Sun's rays are striking the Earth directly at a latitude approximately 23.5 degrees north of the equator (that is, the Sun's rays are coming in at an angle of 90 degrees here; this is the subsolar point). View answerHide answer. 2  The Sun at noon would be 23.5 degrees above the horizon. 3  The Sun's altitude at 23.5 degrees north is 90 degrees (directly overhead). 4  The difference in latitude between the subsolar point (23.5 degrees north) and the North Pole (90 degrees north) is 66.5, and 90-66.5=23.5.
