A very beautiful dust devil was recorded by Mastcam-Z Right in the sequence of the 5th flight of Ingenuity.
Substracting MCZ frames by a frame without the dust devil makes it more visible. -------------------- |

Dust devil alert! (yes, another one). Sol 92, just about due west, right side of this image (NLF_0092_0675115622_792EBY_N0040136NCAM00698_00_0LLJ01_800).

Since this place looks like Dust Devil Alley... I wrote a little workflow program to look for them in the NAV sequences
This is SOL 84 ... (we've seen this --- eyes left) ... the gain is cranked in the program This is Sol 78 ... The program found a near-invisible DD (The blues are darker areas that change color before they are gained... it's a work in progress -------------------- CLA CLL

Another set of images captured by Hazcam and Navcam of one or possibly two dust devils, a good two minutes apart, on sol 102, in the favored spot, in front of the darker crater wall:

Here is a GIF of 21 images (NAVCAM LEFT) for 5 minutes around local noon on Sol 101
It is from a program that looks for dust devils Short Story: there are none close by (but there is something going on on top of the deltas in the center) With the gain turned all the way up -- I suspect I am seeing compression artifacts, exposure differences, sensor sensitivities -------------------- CLA CLL

A more stationary dust swirl on the center of the delta, on sol 107:
Click to animate. The frame spacing is about 14s but played at 0.5s for dramatic effect. quickest workflow: - filter raw images to select frames as specifically as possible. - use bookmarklet to extract list of raw image urls - copy list and paste as wget arguments on console to download, remove urls if necessary - optionally enhance images with gimp or imagemagick - upload images to ezgif.com - use ezgif to crop, enhance, label and optimize animated gif - download from ezgif. -------------------- --

Sol 107 Dust Devil Watch
Finer details still elude the detector so far ... but that delta is far away! 5 minute GIF starting 1:15pm local time Scintillating bits are compression/stretching (?) or real (?) -------------------- CLA CLL

Sol 111 -- Dust Devil Watch
Probable: One very far DD -- far left on the top of the crater rim - persists over several frames Otherwise not much else Gain all the way up - and then some - (very scintillating!) GIF -------------------- CLA CLL
