Explanation:
Last week was another good week for
auroras.
The story began about two weeks ago when two large
Coronal Mass Ejections
exploded off the
Sun.
Waves of elementary particles and
ions swept out past the
Earth
on September 28 and 29, causing many
auroras.
A week ago, a
flapping sheet that divides north and south
regions of the Sun's
magnetic field passed the Earth, again causing auroras.
Pictured above is a particularly good image of one of the
October 1 northern lights.
Taken in
Canada's
Yukon, the city lights of
Whitehorse
are seen below dark clouds and a
twisting green aurora.
