Solar Storms: Rising Threat to Technology  The sun will be
getting more active over the next few years and, reports CBS
News Correspondent White Johnson, scientists are worried about
the possible impact on all sorts of technology we take for
granted, including satellites such storms could cripple.  NASA
says there have been five sun storms in the past century, and
others could be on their way. No one is sure when the next one
could hit, but researchers are hard at work trying to come up
with better prediction mechanisms as they try to better protect
that tech.  The fiery explosions blistering the sun's surface
have energy bursts with the strength of 1 billion hydrogen
bombs.  "Now we are going into the peak of the solar cycle,"
explains NASA's Lika Guhathakurta, "and, as we approach the
peak, what happens is that the magnetic field on the sun gets
twisted and really tense."  Powerful electric charges can be
sent rocketing toward earth.  In 1989, just a minor flare
knocked out electricity to millions of Canadi
