SDO/AIA running difference images in the 131, 94, 335, and 171 Å channels showing the flux rope eruption. S1, S2, S3, and S4 are the slice cuts used for the stack plots. The flux rope contours (green) of AIA 131 Å are overlaid on the AIA 171 Å image (panel d)). The blue dotted curve in AIA 171 Å indicates the cool compression front of the CME. The temporal evolution of the flux rope and the associated flare in 131, 94, 335, and 171 Å can be found in the online movie.
