The moment the #BlueGhost went silent at 23:15 UTC tonight as observed with the Bochum dish: x.com/amsatdl/status/190141699 - ten minutes later Firefly Aerospace distributed the 'final message' x.com/Firefly_Space/status/190 but it isn't clear if or when it was actually transmitted from the Moon. And we also weren't told whether the planned post-sunset observations of the lunar horizon were carried out and whether any data were received before the battery died.

The moment the signal died - here it is already down to half the value before, moments later only silence.

Here is a time-lapse video posted by Firefly Aerospace of the solar eclipse and "diamond ring" seen by the Blue Ghost Lander last night.

The glowing ring of the eclipse is also reflected on the solar panel.

The large ring seen in the reflection on the solar panel is clearly an artifact.

Earth looks small because of the wide angle lens.

#BlueGhost healthily survived the ~2 hours of totality with little sunlight to charge its batteries.

And here it is, the first picture of a total #SolarEclipse from the surface of the Moon since 1967, taken by the #BlueGhost this morning: flickr.com/photos/fireflyspace - remember that this may look like your typical #DiamondRing picture at first, but with a total eclipse from Earth caused by the Moon the latter has the same size as the Sun, and it's the bright inner corona that closes the ring. Here it is the Earth's atmosphere forward-scattering sunlight and totally overwhelming the corona.

Crop but no further processing!

During tonight's total #LunarEclipse the #BlueGhost lander on the Moon will try to observe a #SolarEclipse by the Earth: see fireflyspace.com/news/blue-gho (13 March update) for details. The only such observation from the lunar surface so far had been perforned by Surveyor III in 1967 (left image; see facebook.com/groups/SolarEclip for what's going on) - and even Blue Ghost's wide-angle camera should see at least as much detail of the backlit atmosphere as its March 3rd Earth image on the right demonstrates.

From the #LPSC 'NASA Night' youtube.com/watch?v=Ns4sVQ81Di a list of the next #CLPS missions: NASA will have more Stereo Cameras for Lunar Plume-Surface Studies (SCALPSS) on #BlueOrigin's HLS test lander. They also reported superb results from #BlueGhost with 6 of the NASA experiments already completed and the remainder being done once the hot noon is over. Not much came out of #Athena, obviously, and they're still trying to make contact with the Lunar Trailblazer - no indication of the hope level ...
