Polar: PIXIE at Perigee 2 on May 11, 1999 (South)
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.

*Please note: the SVS does not fulfill requests for copies of the tapes in our library. On some of our animation pages, there is a direct link to a video distribution service from which tapes, handled by the Public Affairs Office (PAO)/Goddard TV, including some of our animations may be ordered. General information on this service can be found here.
