The downward flow of particles
from the Sun causing the Northern and Southern Lights is matched by an
equal yet opposite flow of electrons upward. That flow carries the return
current of what essentially is a
giant circuit. This upward flow hollows out electrons in regions of
the Earth's ionosphere and produces

Jo Ann Joselyn, senior space
scientist at the Space Environment Centre, the space counterpart to the
National Weather Service and Bruce Tsurutani, a physicist with NASA's Jet
Propulsion Laboratory, are producing a research paper about how solar storms
can affect Earth. ...Astronomy Magazine, January, 2000, page 56.
They have found that Northern Lights appear more often when the Sun is
the most active, right around the peak of the solar cycle.
