Propagation of the associated CME observed by the SOHO/LASCO C2 coronagraph. An inverted colour table is used (bright coronal features appear darker). A few features used for tracking the CME kinematics are marked (cf. Fig. 2): the LE of the CME at PA 56° (a), the part of the core marked as core3 (b), a concave feature (c), and a trailing feature (d). The image was produced using JHelioviewer (Müller et al. 2017).
