On Sol 1037 (three days ago) the Perseverance rover observerved this transit of Mars' smallest moon Deimos.
This timelapse shows the event at 10x speed.

If you are wondering what that small dark speck is that moves along with the sun - that's one of many sunspots!

Using drizzle stacking on the images (and masking out Deimos), I was able to make this image that is 3x higher resolution than what Mastcam-Z can natively capture.

Image of the sun - but taken from Mars! The sun is a pale yellow color and has a few small dark spots on it's surface. The largest one is towards the bottom of the disk next to two smaller ones below.

To process the timelapse images I first had to make a darkframe that contained all the static noise pixels dispersed over the frame. After subtracting this noise I converted the images to .dng files so I could edit them in Lightroom.

There I applied Adobe's machine learning based "Enhance" function to upscale these timelapse images 2x. This means the very fine details are not 100% real, but I didn't notice it introducing any artefacts either.

The second image was upscaled using a different method. I stacked these in AutoStakkert, a popular planetary image stacking program. It has an algorithm called Drizzle which can reconstruct real details (like the sunspots) from undersampled images.
This algorithm was initially developed for the Hubble Space Telescope and is often used in astronomical observations.

This isn't the first time the Perseverance rover has viewed a solar transit of one of Martian moons.
Back in on Sol 397 (April, 2022) we got to see this amazing eclipse from Phobos.
