Polar Visible Aurora: Normal Solar Wind Conditions on November 13, 1999 over the North Pole
Visualizations by
Greg Shirah
Released on December 8, 1999
On May 11, 1999, the solar wind that blows constantly from the Sun virtually disappeared. Dropping to a small fraction of its normal density and to half its normal speed, the solar wind died down enough to allow physicists to observe particles flowing directly from the Sun's corona to Earth. This severe change in the solar wind also drastically changed the shape of Earth's magnetic field and produced a rare auroral display at Earth's North Pole.
