R nomenclature (from the IAU and from unofficial sources)

Italics indicate farside features.

- Rabakuw and Rafelon
On page 47 of the january 1979 issue of Spaceflight (a well-known magazine for rocket and spaceship addicts) appeared a curious letter by a certain Geoffrey Hugh Lindop, who wanted to change the entire catalog of lunar nomenclature into some sort of lettered code system. In his letter, he included two examples of his system: Rabakuw (the IAU's Bianchini W) and Rafelon (the IAU's Plato F). After reading his letter about a dozen times, I still don't understand his method. G.H.Lindop's system could be a VERY interesting one (!), but he didn't give much explanation... (or rather: "a much too complicated" explanation) (the two examples were not enough to comprehend Lindop's way of thinking). - DannyCaes DannyCaes May 26, 2017

J.Hewelcke's nomenclature-system for the many ejectarays around pronounced craters, adapted by D.Caes, see: http://the-moon.wikispaces.com/Rays
- Rilles
The IAU's list of named rilles is very incomplete (the moon's far side doesn't seem to exist). Explore a new list of named rilles on both the moon's near and far sides: https://the-moon.wikispaces.com/Lunar+Rilles
