Evolution and kinematics analysis of the CME. (a) The black dashed line indicates the large-scale expanding loops in AIA 193 Å. (b) CME as seen by the COR1 coronagraph. (c) CME as seen by the COR2 coronagraph. (d) Time–height plots of the CME. The asterisk indicates the height. The green and blue lines indicate the lineally fitted speed. The black dashed line and square indicate the extrapolated onset time of the CME to 1 R_⊙. An animation of the evolution of the CME is available online. The animated sequence runs from 01:00 UT to 03:00 UT on 2023 September 11 and its real-time duration is 13 s.
