Time slices through four slits (S1, S2, S3, S4) in different sections of the filament channel observed in 304 Å (SDO/AIA) during the recurrent jet activity from 09:00 UT to 10:30 UT (1.5 h) (top panels) and during the failed eruption between 16:30 UT and 18:30 UT (2 h) (bottom panels). The slit positions are drawn approximatively in Fig. 4. The origin zero is at the southeast end of each slit in the filament, near the limb for the bottom panels. The velocities indicated in the bottom panels are projected velocities.
