Another view of the SOL 148 Event Annotated -- 9 dust devils and a few gusts. The event is 5 minutes long and we have 21 seconds of images. I really appreciate those animations. From memory this seems the most active 5 minutes observed so far in the area. Also, probably the clearest example of dust devils moving in opposite directions, simultaneously, perhaps hinting at local rotating 'supercells' spawning those turbulences. -------------------- --

I finished up some improvements on the DD detector (C++) and tried it out on the SOL 148 Event.
Since this sequence was taken at High Noon at Jezero, there are no long shadows from the actual 'wispy' DDs. So, I think the dark triangular 'mat' at the beginning is low flying dust flung from the passing DD. As the dust settles it takes on the color of the ground. Light colors are more positive image pixels than the Averaged Comparison Image (21 frames), darks are more negative pixels The program is fully automatic: drop the images in the working directory, press the button, and a minute later its is all done. I believe a lot more hand processing would suss out more detail and make it more photorealistic. I included the actual vs processed images as a comparison -- a little extra compression made it all fit into the upload limit. GIF -------------------- CLA CLL
