This video is composed of observations by the Large Angle and Spectrometric Coronagraph (LASCO) onboard the ESA/NASA SOHO satellite from 21 November 2001 to 25 November 2001.

The data was very badly degraded from about 08:30 CET on 23 November 2001 through approximately 10:30 CET on 24 November 2001 as a result of the solar proton storm associated with X-ray flares that erupted on 22 November 2001 and the shock originating from the Coronal Mass Ejection.
