Early Rays of Understanding

I have stumbled upon a largely overlooked Chuck Wood

Another idea from 1935
Also in 1935, Eppe Loreta at the Observatory of Bologna, Italy proposed that rays be named, like craters, after astronomers. Rays have apparently never received any designations, perhaps because of their discontinuous and nebulous nature. I am glad Loreta's idea never caught on - imagine every ray from Tycho being named for some second rate astronomer! Perhaps the present informal way of referring to rays - the Serenitatis ray from Tycho - is all that is needed. Or perhaps rays could be designated with the name of their parent crater followed by their azimulth. Thus the Serenitatis ray might be Tycho 35°.

Still the best review of older ray theories is Baldwin's The Measure of the Moon, Chapter 19.
