Starting from Curiosity Observes Sunset Eclipse: Sol 2358 I found three images in the sequence PIA23133, PIA23134, and PIA23135 which I thought would mean (but don't know for sure) that they are associated with the same event. Several things confuse me, including:
- Why are the eclipsing bodies in PIA23133 and PIA23134 so different in angular size compared to the solar disk? If they are separate events, why are the PIA numbers adjacent?
Why is it that it's mostly a chunk of the right half of the sky that darkens during the eclipse in PIA23135?per suggestion I've moving this part to Astronomy SE: Why is only a narrow chunk of sky darkened in this amazing Curiosity solar eclipse GIF from Mars?
For this particular question, please include some specific information on these images with a link if possible, rather than just a best-guess answer. Thanks!
Enquiring minds want to know!
fyi in case you are wondering, per @MarkAdler's ultra-concise answer
They use neutral-density filters to look at the Sun, which reduce the light by a factor of 100,000. The two Pancam cameras each have one neutral-density filter, with the left one filtering blue and the right one filtering red.
