Extrapolation of the DIRECD cone (blue mesh) to STEREO-A COR2 images at 12:23 UT (left panel) and 13:23 UT (right panel). The green line represents the main axis of the cone and shows the direction of CME propagation. The green marker indicates the extrapolated height of the filament, and the red marker at the top of the red line indicates the same for the CME front outer edge. The cone approximately matches the shape of the CME, with fainter CME parts corresponding to far-side cone projections (orange arrow).
