I stumped Perplexity. Can anyone else help?
RE: I stumped Perplexity. Can anyone else help?

Using Stellarium, I got a sun crossing the 0° inclination at 2018-09-18 09:28:40Z, using Wikipedia's lat/long for the crater.  I think it would likely be later than this, because you're in a crater, so there's some hills on the horizon.

If you're at the deepest point of the crater, you're 4.7km down, in an 85 km diameter crater, so you'd get an additional angle of...

θ = tan⁻¹ 4.7 km / ( 85/2 km ) = 6.31°

But some of this will be taken up by the Moon's curvature, so let's get its portion of the circumference

42.5 km * ( 360° / 10000 km ) = 1.53°

For some reason I feel like this is the same angle as the horizon due to some geometry but I'm not going to even try without a piece of paper, just accepting the number  So depending on your altitude, you could need to get up to 4.78°, which could be as late as 2018-09-18 22:40:37Z ... though you'd see the sun on the other side of the crater first.
