My take on this awesome shot of Ingenuity in front of two distant dust devils, and in animation.

SOL 215 B -- the 2nd DD sequence of that SOL ... and a strange one
30 Frames -- 1 stance -- 27 minutes long! -- 10:56 AM to 11:23 AM
The timing between frames is roughly: 33 sec -- 84 sec -- 33 sec -- 84 secs -- etc.

Gusts and Dust Devils!

EDIT: the 3rd DD sequenceof that Sol at 3:10 PM had no DDs

There's one a bit like that on MSL.... take three frames - wait a minute - take three more. The three frames get you motion of any DDs in the scene - the minute wait the spreads them out to get more temporal coverage.

Perseverance has been exposed to winds, gusts, and vortices for 200+ Sols
These 'containers' are associated with the mast stowage prior to landing ( i think ...)
Now they make excellent particle collectors... I hope to revisit them every few hundred Sols

Yes - the RSM was stowed against these before being deployed - that's the left Navcam and MastcamZ cover you're looking at.
