That is a nice set. Since it is distant, a bit small, but nice. When PDS versions of these are available in a year or so, it would make for a great super-resolution image. Voyager 1 got a very similar shot during its approach.

This might be best evaluated by Ted Stryk and Phil Stooke. For Phil, I was wondering if the area marked with the pink ellipses in these two perspectives was identified as a candidate impact basin from Voyager imagery, and if not, if it looks like a very degraded basin to you. For both Ted and Phil: could it just be artifacts from the sharpening process?

I'm no Phil or Ted (PoT), but the feature is also visible in Ted's super-res view as well as subtly outlined in your 2005 view. My money is it's a real feature. Curiously elliptical, though.

The right-hand side looks like one, but I think that it may be part of a larger, rounder structure - I am not convinced of the left-hand side. Whatever it is, it must be old!

Okay, I'm just glad I'm not seeing deceased religious figures in the proverbial spaghetti. The right-hand side is more convincing to me as well. I think the left-hand "margin" I outlined is more likely a coincidental string of relatively fresh craters.

Yes, the left-hand side appears to be a string of craters. See also this image which is lage enough to show this.

The feature was not identified as a basin before. It is faintly visible in the best Voyager images of the area, but only as an albedo marking. I would want to see it near the terminator before concluding that it was really a basin, or whether it's really elliptical. Only half of it is clearly seen, and it might be more circular, but affected by some overlapping feature.
Phil -------------------- ... because the Solar System ain't gonna map itself.
