Multiple snapshots of the dynamic ejections. The white arrows marked (a) show the general direction of the approximately up-down motions. The position of the slit used in Fig. 8 is marked (b). What appears to be the initial plasma sheet is highlighted using the two white lines marked (c). A motion of some upwardly ejected blobs – (e), (f), (j), (k), (p), (r), (s) and (v) – and downwardly ejected blobs – (d), (g), (h), (i), (m), (n), (t) and (u) – are marked with white and yellow horizontal arrows respectively. The region inside the blue boxes marked (o) is used in Fig. 9. See online movie of this figure.
