South Ray is one of the high-albedo ray craterlets near Apollo 16's landing site which are already observable through common telescopes. The best time to observe both ray craterlets (North Ray and South Ray) is during Full Moon. It is not known if the much smaller Baby Ray (near South Ray) is also detectable through powerful telescopes. A good specialist of telescopic Hi-Res webcam photography could come up with the answer...
This crater (South Ray) is a very fresh simple crater, 680 m in diameter. Samples collected date it as 2 million years old, the youngest material collected during the Apollo missions.
