Finishing work in and around Seitah, sols 238-378 Options

Given the haze obscuring the hills in the background could this be dust?

Various grains in a sol 315 SuperCam RMI photo mosaic.
At first I was puzzled why the overlapping parts of the individual images fit together so badly.
Then I found out that many grains changed orientation or moved between the takes (time intervals 10 to 13 minutes).
So a grain with a dimple can be seen twice in the SuperCam photo mosaic (arrows). Here is also an animation for this.
Did we have windy weather on sol 315? What does the weather report say?

It think it's more of a dusty day Olivier

See the full panorama taken on Sol 313, especially the mountains under the Sun. Big patch of sand were blown away.



3 sols later. A more homogenous sky, suggesting the dust load has risen since.



(And a pretty sunset on Sol 318)

More evidence of a presumed short-lived dust storm on day 315.
Sol 316 Hazcam: The lens of the Rear Right Hazard Avoidance Camera (Hazcam) is apparently covered with orange dust. Hopefully, this will not complicate hazard avoidance.
Sol 318 Mastcam-Z image: The rim of the drilling powder was partially blown away, and granular material was accumulated in the abrasion patch (raw image and enhanced).
Judging from the image, the wind or storm came from an easterly direction.

Tau, this is another good demo of aeolian transportation in action. It acts long-term and shorr-term.

Sol 319 evening images of Phobos by Mastcam-Z.
Sun and stars appear to rise in the east and set in the west, the opposite is true for Phobos. It rises in the west and moves rapidly east about twice a day.
The opposite apparent motion of Phobos and two stars can be seen in this animation. View direction is southwest. Time is local mean solar time.
The track of Phobos is overexposed, but the night side of Phobos can be seen to the left of the track, illuminated by light reflected from Mars.

The performance of MZ at night looks similar to MSL mastcam, as expected. Here's a stack of two differenced images, where the differencing removes most of the noise:

The field is in UMa, including the famous eyesight-tester pair of Alcor and Mizar at bottom. The stars are, of course, trailing in a weird direction, for those familiar with Earth's sky.

This is my circular pan of the current area with three nearby features identified.

Bravo Damia for this very nice panoramic image.
And also for the nice 360° sky images and the sunset pan!
