QUOTE (tolis @ Dec 14 2013, 02:47 PM)  it looks like it landed near crater Laplace F, south of Montes Rectii. seems to be in a flat area of Mare Imbrium between Laplace F and le Verrier |

The landing site is at 19.51 deg. West, 44.12 deg. North, per reports from the control center.

Xinhua news agency has announced erroneously that “Chang'e-3 landed on the moon's Sinus Iridum, or the Bay of Rainbows, at about 9:12 p.m. Saturday,
making China the third country in the world to carry out such a rover mission after the United States and former Soviet Union.” This is wrong location as the Mission Control panel screen showed it landing well to the east of Sinus Iridium, in Mare Imbrium. My estimate of the landing coordinates, from the low-res screen, is in the area of 19 degrees West, 45 degrees North. That would put it about 25km SE of the ~7km diameter crater Laplace F, near a ridge or scarp, and a couple of other craters of 2km diameter. So there might be some topography in view. (written before previous announcements!) |

Looking to the following CNTV screenshot, it seems that actual landing point is the rightmost one in the green box, presumably showing the previously selected potential landing area...

And the first image from the lander's monitoring camera.

Any chance the landing site is in an existing LROC frame?

Very good chance, the whole area is blanketed with images, and Chinese scientists downloaded them all in that area (confirmed by LROC team) and will have chosen a site which is well imaged.

Good day for the home internet to go down! Also real life is getting in the way, but I should be back in my protective bubble soon. Phil -------------------- ... because the Solar System ain't gonna map itself.

 I break my long hibernation from this group  to post a quick mosaic of some of the descent camera frames. I corrected the proportions to have square craters. There are some more distant frames that could cover a larger area. -------------------- _______________________

Well, I've identified the landing site.
Lat: ~44.1260, Lon: ~-19.5014. Using http://target.lroc.asu.edu/q3/ and matching it to several of the descent camera images. See below.
