I can see why they termed it nodular.

Hey, could you help me ?

On Sol 2767, Curiosity took a very odd image. I've just unbayer it, so we can see that it was taken under blue filter. Given the time at this location, it was during the night.



An other pic, cropped and a bit cleaned up.



Problem is, I don't have any clue of what is that object. Could be Phobos, but after a simulation in Stellarium, this moon was just setting. And Deimos is too small to be picture with such resolution. But maybe Stellarium wasn't very accurate about the exact location of Phobos in the sky. So, I don't know…

That looks like a mid-morning image [*] through the solar filter taken as part of a dark current measurement. I'd expect the image aim to be at nearby ground. It would be a very long exposure--typically they are a set of 0-sec, short, and long exposures. The solar filter transmits ~0.001% of incident light, but the one in M-100 has a couple scratches or pinhole defects that let light into the system. And yes, the artifacts are blue because the M-100 solar filter is paired with a 440-nm, narrow-band filter.

The artifacts have been around since the start of the mission. Sun images are designed to miss them--at least they are conveniently off-center. See also: Bell et al 2017 (https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2016EA000219) section 4.2.7 (pinhole) and 4.2.1 (dark measurements).

* I see just after midnight UTC, which is a bit before 9 AM that sol.

Yeah, we don't have the LMST publicly yet for that image (without calculating it ourselves of course), but it was taken at around 0:29 UT, which is only a few minutes before this image was taken, which is clearly daytime:

Thank you both for your answers smile.gif

It explains… A LOT actually. I suspected something like this but I was like "Come on ! A hole in a solar filter ? Makes no sense !". I was wrong…

As for my Stellarium simulation, I don't understand where I made a mistake. I input the correct location, the correct time, and this gave me nighttime. Not daytime. I should dig deeper to find where I made a mistake…

But again, thank you smile.gif

A bit quiet lately as Curiosity digests its Glasgow lunch. This shows where and when a few events happened:

I should point out that my 'sample dumps' include the sprinkling of small amounts of material as well as the bigger dump on the last sol.

Now it's time to get moving again.

Back to the RMI observations of Gediz Vallis Ridge: I eventually finished stitching together several RMI sets and colorized them with MC Right pictures. More mosaics to come!
