3D reconstruction of the erupting filament between 11:05 and 11:35 UT in Solar Orbiter/EUI (SOLO), STEREO-A/EUVI (STA), and SDO/AIA 304 Å base-difference images. Column 1 includes both the Solar Orbiter and Earth times to facilitate comparisons with Earth-based observers. The red marker shows the upper tip of the filament, which matches in the three viewpoints. Epipolar lines are shown in green. Blue markers indicate the points along the filament used for the 3D reconstructions of the filament loops at 11:15 and 11:25 UT in SOLO and STEREO-A base-difference images.
