I just posted the following to Robert AM*'s Fartbook page:
===================================================Here, by the way, is the over-brightened version, and there's the smudge he thinks is Big Ben, on the limb of the Moon (zoom in.)
The image containing the feature you call "Big Ben on the Moon" is AS17-M-2366.
You have made yet another nomenclature error, and yet another image interpretation error. This is not, as you said, MAGAZINE M. All images from that mag would have the ID AS17-142- followed by five digits. Instead this is from the Mapping Camera, revolution 65. The location of "Big Ben" if it existed would be NE of crater Neper. Please check the LRO image library to see if you can find a clock tower.
Your image interpretation error is that you examined a bizarre version of this image, not realizing that it was over-brightened, Here is a correct version FYI.
And I thank 'Trekker' who found this for us and did the geo-location (seleno-location?)
Update 3/18: Today I asked the star of the morning what he thought the thing actually is, and what he estimated as its height. He replied that it was definitely not a clock tower -- probably an Earth observation post, or a Tesla tower. Although he promised to answer the second question, he never did.
Update 3/20: Happy Vernal Equinox.'Trekker' points out that in the very next frame, AS17-M-2367, Big Ben has floated off into space. I posted this comparison of the two frames to FB-AM*.....
