----------------------------Original message---------------------------- 180 degrees from sunrise to sunset could never happen north of Cancer or south of Capricorn. Regardless of the time of year north of Cancer, sunrise is still in the southeast with sunset in the southwest, just at varying degrees. South of Capricorn, sunrise is always in the northeast and sunset in the northwest. Only between Cancer and Capricorn could you ever have 180 degrees from sunrise to sunset since it is only in that range that the Sun would ever pass directly overhead. At least that's as I understand it...
