From: Observing Kelvin–Helmholtz instability in solar blowout jet
Evolution of the jet observed by IRIS 1400 Å. (a) IRIS 1400 Å slit-jaw-images (SJIs) displaying the development of the jet. The green boxes in the second and fifth panels outline the brightenings. The blue dotted curve in the fifth panel denotes a “cavity” within the jet. The green line AB shows the cross-cut position used to obtain the stack plot which displays the jet’s width variation over time, as shown in (b). The green dashed lines denote the outer boundary of the jet that reached 19.7 Mm in height by the end. (c) Evolution at the position of curve CD (see panel at 19:32:38 UT in a) which passes through the cavity and the bi-directional flows (see panel at 19:33:29 UT in a). The velocities of selected representative bright structures are displayed. (d) Temporal evolution of flows at the position of curve EF (see panel at 19:36:41 UT in a). The flows from right to left (1−3 in cyan color) and from left to right (4−6 in green color) are shown in this plot.
