Selected snapshots of the CME evolution on 13 March 2023, as seen in coronagraphic observations from LASCO and STEREO-A. Each panel shows an overlay of a plain coronagraphic image and the corresponding running difference image at the same time from LASCO-C2 (panels a and b) and COR2-A (panels c to f). At selected frames we note the CMEs and outline the location of the CME-driven shock wave. The interaction of the shock with streamers (S1 and S2) are also noted in panels d to f (streamers deflections S1D and S2D). The various features are discussed in detail in Sect. 2.
