A
Magnetic Storm Rips Through Earth's
Magnetosphere
During
the month of March, 1989, a scientist strolling
outside Arizona's Kitt Peak National Observatory
observed a red glow in the night sky that
he thought was caused by forest fires.
Then, seeing a greenish fringe and vertical
streamers stretching like ribbons above
the horizon, he realized what it was – the
aurora borealis, or Northern Lights.
It
was very unusual to witness this mysterious
and awe-inspiring phenomenon so far south
of the arctic region, where they are a
common sight. Their appearance on this
night was made possible by a series of
events that began several days before on
the Sun's surface, some 150 million kilometers
away. The 1989 magnetic storm caused a
blackout of the Hydro-Quebec power system
in Canada, leaving 6 million people in
Canada and the U.S. without power for nine
hours.
