NASA Report: 
Solar Storm Sheared Earth's Atmosphere at the Arctic on Sept 24, 1998
  
Creating an ionospheric fountain of outflowing oxygen and hydrogen ions. A "polar plasma fountain" and a massive aurora borealis display.

 

 

Aurora as seen by Polar UVI Instrument - After The Ultraviolet Imager on NASA's Polar spacecraft captured this view of the aurora as seen from space on September 24-25, 1998. Auroras are typically seen from the ground only at night, but they in fact spread around the day and night side of Earth's north and south poles. Viewing the auroral oval in ultraviolet light allowed researchers to confirm intense activity on the day side of Earth, where the plasma from the ionosphere was squeezed out into space.
