    NOVA: "Magnetic Storm"
    On March 13, 1989, the lights went out all across Canada, and the
    eastern seaboard of the U.S., as far south as New York. The most
    serious power grid failure in American history was caused by a
    magnetic storm in the earth's upper atmosphere, itself triggered by
    the eruption of a huge flare from the surface of the sun. Unusual as
    this event may seem, many scientists, today, are beginning to worry
    that it may be a harbinger of things to come, and that changes to
    the planet's magnetic field could make earth ever more vulnerable to
    deadly radiation from space. This program explores one of the
    least-known, but most serious, threats to life on earth. [TVG] R on
