    Re: Definition of Arctic Circle

    Here is a link to a page with a definition:
    That page has another link to an article on the wanderings of the
    Arctic Circle.
    The Encyclopedia Brittannica says that the Arctic Circle is a
    parallel, or line of latitude around the Earth, at approximately 66?30' N.
    Because of the Earth's inclination of about 23 1/2? to the vertical, it marks
    the southern limit of the area within which, for one day or more each year,
    the Sun does not set (about June 21) or rise (about December 21). The length
    of continuous day or night increases northward from one day on the Arctic
    Circle to six months at the North Pole.
