Observations from Solar Orbiter (reprojected to Earth’s view), SST, and IRIS showing a fibril singularity and a blow-out jet around 09:40 UT. The Solar Orbiter/PHI magnetogram (left panel) shows the sunspot’s moat flow, containing small-scale magnetic patches (see the attached animation). The black arrow in the SST panel indicates the chromospheric material ejected from the peeling of the arch filament system. The white box shows the field of view of Fig. 3. This figure is associated with an online animation (PHI+SST+EUI+IRIS_2023-10-20_fullfov.mp4).
