Difference images of the AIA 193 Å filter at two different times to visualize the propagation of the CME. The left panel is an image from a running-difference movie during the impulsive phase of the flare, and the right panel is a difference image taken 35 min after the flare onset. A preflare image is subtracted to identify the dimming regions. The diagonal lines in the left panel are diffraction patterns. The red 40% contours show the location of the four sources as seen by AIA 1600 Å in the impulsive phase for reference.
