Update on February 18th:

-------------------------------------

UHF Satcom ‏@uhf_satcom

Nothing again tonite on X-Band from either the Yutu lunar rover or the Chang'e'3 lander - will check again tomorrow!

-------------------------------------

The same (very useful) source detected nothing last month as well. Note that the negative result only applies to the specific times of monitoring, and there may have been activity when uhf_satcom was not facing (or listening to) the Moon but China was in contact.

Thanks! That is very useful.

If you check out the link in the post above, there is a new image of the lander from the rover. It seems to have been taken in March 2014 from Yutu in its final resting place, and this is the first time I have seen it.

UHF Satcom ‏@uhf_satcom 2月22日
Another quick FFT of Yutu Rover X-Band downlink - nothing detected from Chang'e'3 lander or 7GHz uplinks.

UHF Satcom ‏@uhf_satcom 2月22日
Yutu Lunar Rover is back in town! A massive signal on 8462.053MHz complete with sidebands, maybe low-rate data.

UHF Satcom ‏@uhf_satcom 10 hours ago [ = the night of the 17th/18th of May ]

No signals from Chang'e'3 lander or Yutu Lunar Rover tonite - caught a glimpse of 8496MHz lander downlink last night but it was short lived.

(PS: UHF Satcom is in the UK, so transmissions when Chang'E 3 and Yutu are visible in China but not in the UK will not be detected)

UHF Satcom reports no contact with Chang'E 3 or Yutu in June.

Great 360deg panoramas from Chng'-3 and Yt!
Put them full-screen, and you really think you're there!

An image of earth is just plopped in there? Or there was a massive hurricane over Texas?

Earth and Sun are faked obviously...

According to this, Chang'E 3 has survived its 35th lunar day (September) and operated through the lunar eclipse on September 16, apparently using its telescope for astronomical observations during the eclipse.

Today, May 6th, Chang'e 3 is expected to wake up for its 43rd lunar day. There is a schedule of day-night cycles here:

http://iloa.org/media/Chang'e3_Lunar_Day_Night_Cycle.pdf

That is from the International Lunar Observatory Association which has a data-sharing agreement with China to use its UV telescope data. The list was issued in February so presumably the lander was active at that time.

Looking back at the lander panoramas, this is a circular version of a panorama to show the distance to some horizon features. The western horizon was only a few hundred metres away, but several distant hills showed above it (see post on the page before this on the forum). The eastern horizon was between 2 and 4 km away with some crater rims visible, and to the north some distant topography showed above a nearby crater rim. The next image tries to identify the more distant features.

These maps zoom in to the lander location. In the first image some distant craters are indicated which appear to be the distant hills in the circular panorama. The northern hills might be crater rim or the ridge north of the crater.
