• Movie 1: 29 July 1996 CME as observed by the LASCO C2 coronagraph. The CME occurs on the West limb beginning as a brightening on the lower edge of the pre-existing streamer. Each frame has had a background model subtracted, and a radial filter applied.
  • MPEG movie (~0.13Mb)
    
  • IDL Movie File (binary file, ~17Mb) (cf. instructions on viewing)

• Movie 2(~0.08Mb): Simulation of the 29 July CME as seen in the LASCO C2 field of view. The simulation results are displayed as polarized brightness.

• Movie 3: 29 July 1996 CME as observed by the LASCO C3 coronagraph. The CME occurs on the West limb. The propagation through the C3 field is not well tracked due to the data gap discussed in the text. The CME is seen to propagate to 32 Rs, at which point is has developed into a disconnected structure.

  • IDL Movie File (binary file, ~16.5Mb) (cf. instructions on viewing)

• Movie 4(~0.06Mb): Simulation of the 29 July CME as seen in the C3 field of view. These model results show the calculated polarization brightness, and clearly show the development of the disconnected structure.
