1707 drive, was expected to be ~30 meters, no news yet on actual distance. Here is the L-NavCams mosaic from the available frames
EDIT: Midnight Planets reports the drive as 13.6m S (-177º) Link to 15 frames from the L-NavCam Link using MS ICE (stitching errors) but we look well short of the expected 30 meter in the plan |

Thanks for that, Paul - using your image and Hazcams, I think we moved roughly 13 m southeast.

According to the ephemeris, the shadow of Phobos passed to the south of the rover and over the mound at this time. I don't see anything that is obviously dust activity in the wake of the (very small) thermal effects of the shadow. Now that all the navcams from that 1694 sequence are in here's an animation of all frames showing the penumbra. (The remaining frames show no differences above noise.) I've done a multiplicative rescaling of the overall intensities of the first frames so that the foreground brightnesses match, on the assumption that MSL was outside the penumbra. (It's worth stressing that this isn't proper calibration, just an ad hoc correction for exposure variation.) We can see the penumbra slip away. The dark highlights on some rocks in the first frame are probably due to specularish reflections of the darkened sky. |

Close-up at "Prays Brook": One image from sol 1714, features what will eventually be a focus merged 'Dog’s Eye MAHLI Mosaic' along "Prays Brook" to characterize the contact between the dark gray rocks found in this location and the underlying typical Murray formation. I have added a 50 millimeter scale bar below the mosaic *based on Gerald's 'MAHLI ruler', this should be applied to the 'in-focus' sections only, I plan to assemble the mosaic once the raw frames come down, unless someone beats me to it

Are those grey rock layers some sort of ash? Or more mudstone? There seems to be an uncomformity with the lower layer.
