Midnight Planets reporting that Curiosity moved approximately 46.2m SSE (161º) on Sol 1172. LINK Quick and Dirty L-NavCam using the 5 available frames (MS ICE), reduced ~10% to get within the UL limit

Looks like on Sols 1174, 1176, and 1178, Curiosity reimaged a small outcrop of bedrock for dust movement.
Bagnold Dune Monitoring - Sol 1176 by Justin Cowart, on Flickr Interestingly, it looks like there was some wind movement between Sols 1174 and 1176, as most frames show at least a couple white clasts moving between frames. I don't see similar movements between Sol 1176 and 1178. Here's a preview gif with the frames aligned. It's pretty heavily compressed to get it down under the 1mb limit. It should still be sufficient to see some of the larger clasts moving. Here's the full size version with less compression. There are a few smaller clasts also moving around. Due to artifacting in the public data, it's really hard to tell if smaller grains are moving, or if it's just the larger white clasts. It'll be interesting to find out over the coming weeks! |

Very interesting, I think there are 4 definitive areas of movement...I find it very interesting larger "clasts" would be moved by wind vs smaller particles. A few of the moved particles also cast some shadows, which further prove the movement. Maybe these are made from a mica-like mineral which is extremely light and thin... or they are just bugs :-) either way...something moved :-) |

The thing to note is that the particles moved in opposing directions which would make wind induced movement a little suspect. I would not discount Curiosity caused vibration as the influence in this particular case. |
