Metis and EUI view of the 16–17 January 2021 CME, showing both the SR at the start of the event as seen by EUI/FSI 17.4 nm and the CME at a later time, when it was almost fully within the FOV of the Metis UV channel. The panels in the top row show a time series of close-up EUI/FSI images that correspond to the green box in the larger-scale image below. The EUI/FSI images were processed with the multi-scale Gaussian normalisation (MGN) algorithm (Morgan & Druckmüller 2014) to enhance small features, while the Metis image was processed with the normalising radial graded filter (NRGF; Morgan et al. 2006) to emphasise structures over the strong gradient of coronal intensities.
