Eruption of a bright structure (corresponding to the prominence shown in Fig. 4) observed in FSI 17.4 nm base-difference images taken on 2021 February 12 at the different times given in each panel. The image taken at 15:15 UT was subtracted from each of the original images to reveal the evolution of the coronal structure during the eruption. An online movie showing the event is also available. The images and the movie were created with the JHelioviewer software (Müller et al. 2017).
