Others may have reported on this, I dont know, but it does not matter - the more exposure these things get, the better.
This AS15_87_11703 and some others, shows Carmichael (formerly known as Macrobius A) and Hill(Macrobius B).
This is a strange photograph as it seems to have been changed by NASA over the years since it came out. We have the recent one which is here in the lunar atlas and as a jpg high res photo neither of these appear to have "the item" in the yellow circle.
b) Keith Laney has it (where I found it) and more to the point, c) 31st May 2005 LPOD has it too. and "the item" clearly has (landing) legs and is craft-shaped.
Now, I dont know if this is one picture copied many times, by different people, but they all have it and now it is gone, so either it WAS there and now it has been sanitised or it was never there and someone just added it in and other got taken in by the deception and copied it.
