Abstract
THE recent discovery1 of a characteristic red luminescence when enstatite achondrites are bombarded by 40-keV protons led Kopal and Rackham2,3 to observe the Moon in order to determine whether a similar luminescence might be excited in lunar materials by solar wind bombardment. On the night of November 1–2, 1963, Kopal and Rackham observed an enhanced red emission from the vicinity of the crater Kepler. The duration of the red glow was of the order of 10 min or longer, and it appeared twice within a 2-h period. No repetition of this phenomenon was observed on the following night or at the next lunation.
