Bill, Thank you for your reply. I have both the impact crater and the adjacent volcano, located now, with practically the same name, it can be somewhat confusing.

I have just noticed that cover photo to ‘Atlas if the Moon’ Wood and Collins, shows both the impact crater and the volcano, designated Mairan T, both are shown together with their correct designation. I’m not sure who names features on the Moon, but giving the crater and the volcano much the same name is confusing. I also note the description inside the atlas that refers to the volcano with a crater on top, this could easily lead one to conclude the feature top most on the volcano is an impact crater, but that is not the case.

Paul, Thank you and I had seen that Wiki reference, but I was after Mairan T, not the lunar impact crater, Mairan, it’s a bit confusing. I’m interested in the lunar volcano, designated as ‘the silicic volcano Mairan’. Interestingly some descriptions give this as an impact crater or crater, but it’s not, more a collapsed volcano caldera.

Paul, The feature is the silicic volcano Mairan T (41.79°N, 311.61°E). I was trying to understand those coordinates and locate it on a lunar map and in a lunar atlas. I will now take your suggested West coordinate and try and locate it.
