Hello,
From the posts below...
Indeed, as Alcaray wrote, it can't be seen from the Earth and if it's seen from another angle, the Moon will appear another way!
M31, being very high in the northern sky, I chose a day when the Moon and M31 would be one on top of the other (by chance it was december 28th at 02:44 AM CET) and located the observer about 298,000 km above the Earth's south pole (precisely a point due south of California, about 80 degrees south.)
Then I looked for the Moon (with some minor adjustment) and M31:
Because it's from way below the south pole, the Moon is upside down.
And zooming towards the Moon, we see its south pole much better than we could from Earth:
Here the Moon is the way we'd see it from the northern hemisphere.
The Moon and Andromeda together with Starry Night...!!!
