Splitting filament of 2023 February 5 seen by SolO/EUI FSI304 (a) and SDO/AIA 304 Å (b) at 14:35 UT. Panel (c) shows an image from SolO/EUI FSI304 at 14:42, when the splitting is advanced. Schematically the reconstructed areas are indicated by lines projected in the different images. In panels (a) and (b) the lighter green and gray dashed lines indicate the eruptive and confined segments, respectively, corresponding to the same color dots of panel (d). The darker green and black dashed lines of panel (c) indicate the reconstructed area also displayed in panel (d) with dots of the same color. In panel (d) the 3D positions of the triangulated pixels at 14:35 and 14:42 UT are shown with the closed magnetic field lines (white) in the area of the eruption, with the segment colors indicated above. An interactive version of this figure is available online, which allows different rotations and projections of the triangulated dots. The interactive figure also includes negative-polarity open field lines surrounding the area, which are not displayed in the static figure to simplify the visualization. The gray sphere represents the solar surface at 1 R_⊙, and to provide orientation the equator (teal), SolO meridian (yellow), STA meridian (pink), and SDO meridian (turquoise) are displayed.
