The EIT instrument is witnessing here the beginning of a spectacular chain of events. Initiating with an explosive flare, a density wave is propagates across the solar surface.Shortly afterwards, the LASCO-telescopes observe a major  mass  ejection   being launched  in direction towards  the Earth.The associated magnetic cloud reaches the Earth three days later and there causes  a perturbation  of its magnetosphere,  a so-called  magnetic storm.The  movie  shows   running  differences  between successively taken images.This technique is particularly sensitive to temporal changes in the images.The  primary  images   were  recorded  at  a wave  length of 19.5 nm due to emissions of chromospheric Fe XII ions.

The halo-event  from  the 7th April 1996 as  seen by LASCO-C2 in white light. The sequence of images shows difference images relative to a reference image taken at the beginning of the sequence.
