SDO/AIA 304 Å images of the erupting filament taken at 13:13:53 UT (a) and 13:21:53 UT (b) on 2 April. The blue cross indicates the top of the filament used to track the eruption. Each distance from the disk centre (in arcsec) is reported against time in panel c, after removing the solar rotation (see text). The two vertical black dashed lines indicate the start and the end of the EUI/HRI observation window.
