post 2287 on this forum page:

http://www.9ifly.cn/thread-5819-115-1.html

gives a summary of the mission including confirming what I had thought, that in May autonomous hazard detection and avoidance was tested on Yutu 2. It includes two images of a route map which I will se to update our map, when I can get to it (I'm on the road at the moment).

Andrew Jones directed me to this drive diary for the 9th day:

It includes a mosaic which can be roughly reprojected to give this:

The day 9 tracks are at left. The diary describes efforts to analyze the odd material in the crater (open in Chrome for a rough translation).

Here I show an interpretation of the pattern of tracks. Not sure I have it right. The mosaic is from the end of day 9.

Map update will follow when I can get to it (I'm on vacation in Brittany)

I'll assume that the first image below is a track-image of where Yutu-2 pulled back (because of the first VNIS wasn't suitable), and then progressed forwards to conduct a second view as highlighted below in the second image (colouration is simply for clarification of the area concerned).

Also, I'm assuming, the highlighted sector (on left of the third image below) is relative to the sharp angles pronounced in Phil's image.

This link is to a rover diary for lunar day 10. Using Chrome to translate, it seems that some technical issues had to be overcome (sun sensor and knowledge of attitude) so not much movement this month - Andrew Jones tweeted that the drive was only about 5 m. Yutu 2 is still near the small crater with a bit of glass in it (and there's a photo of the sparkly glass in the article) and either made a new analysis with better lighting or is going to do that before they leave.
