The formation of the post-CME CS as observed by the two Metis channels. Left: zoom over the post-CME CS as observed by Metis on February 13 between 02:38 and 06:38 UT in the UV (top) and the VL (pB, bottom) channels (see also the bottom right panel of Fig. 7). Right: normalized UV (blue) and VL (red) north-south intensity profiles as obtained at 02:38 UT (top) and 06:38 UT (bottom) by averaging east-west between −5.4 R_⊙ and −4.4 R_⊙ (see text for explanations).
