| <p>Paolo Amoroso is the #1 contributor of images to the LPOD [http://www.lpod.org/coppermine/ Photo Gallery]. Every day he cuts an image of a named farside crater from the Clementine mosaic at Map-A-Planet and uploads it to the Gallery. Yesterday he submitted an image for Kosberg, a 15 km wide crater at 20.2°S and 149.6°E. This is a small crater within the larger farside crater Gagarin. When I saw his image I wondered why such a small crater had been named, rather than lettered. Good nomenclatural practice does not place one named crater inside another. When I pulled out the <em>Clementine Atlas</em> I realized that the bright crater Paolo selected was not the crater of the IAU coordinates. The Apollo 15 mosaic made for the <em>Apollo 15 Flight Journal</em> beautifully depicts the area. The crater at the coordinates of Kosberg is hardly worthy of a name, whereas the nearby fresh crater that Paolo selected is a very good landmark at all illuminations. The IAU added the name Kosberg to an inappropriate crater in 1976, when the IAU lunar nomenclature committee was chaired by a person (D. Menzel) who was ignorant of lunar cartography. Later that year he died, but many poor nomenclature choices remain memorialized on the Moon, including Kosberg. No name is needed - the IAU should have found a crater worthy of a name. Paolo’s crater is actually designated Gagarin G, a proper level of naming.</p> | | <p>Paolo Amoroso is the #1 contributor of images to the LPOD [http://www.lpod.org/coppermine/ Photo Gallery].
