I set up this scope this evening with plans to image the GRS shortly after 1 am then to image the new impact site when it transitted at 3:25 am. I screwed up and lost the first few images of the GRS transit by forgetting to rename them.
Here is the first image at 1:30 am. 
Note the prominent spot to the northeast of the GRS. Seeing was not good, maybe 4/10 so it was difficult to judge the size as bouncing around a lot. Even so, it was clearly visible on the monitor and through the eyepiece.

Here is one from 3:08 am, note the impact from a few days ago can be seen near south pole.
Next one from 3:15 am mdt, turbulence improved to maybe 5/10.
And finally 3:53 am, shadow very near the limb:
