Evolution of the splitting filament on 2022 October 28, seen by SolO/EUI FSI304. In the first panel, the white arrow indicates the rising filament. In the central and right panels, the green arrows indicate the eruptive segment, and the black arrows indicate the confined segment. The right panel shows the last stage of the separation, with brightenings also observed in hotter wavelengths. An animation showing the filament rising and splitting from 4:20 to 18:00 UT is available in the online version. The animation includes different views. The first, running from 0 to 8 s into the animation, is of the SolO/EUI FSI 304 (left) and 174 Å (right) evolution starting at 4:20 to 08:20. The second portion from 8 to 21 s is of the STA/EUVI 304 (left) and base difference 195 Å (right) evolution during the same period. Then, from 21 to 35 s, the SDO/AIA 94 (top left), 131 (top middle), 171 (top right), base difference 193 (bottom left), 211 (bottom middle), and 304 Å (bottom right) animation is presented. Last, from 35 to 39 s, the evolution from ∼4:20 to ∼17:50 in the FOVs of STA/COR2 and LASCO/C2 is displayed.
