Description
Originally a list of craters with prominent 'ray' systems, this seems now to include bright craters with or without rays. This is far from a complete list! Please add other craters with rays. Thanks!
List of Ray Craters and bright (high albedo) spots
- Many nearside descriptions are from Elger, 1895, but his east and west have been reversed to match the modern convention.
- farside craters in italics
A
- Abulfeda E - A bright crater WSW of Abulfeda A. In ALPO list of bright ray craters.
- Aratus - A very conspicuously brilliant crater in the Apennines, with a smaller light-surrounded crater W. of it.
- Agrippa - Exhibits faint rays.
- Alfraganus - A light-surrounded crater with rays.
- Almanon - About midway between this and Argelander is a very brilliant little crater.
- Alpetragius B - A conspicuous light-surrounded crater, one of the most remarkable on the moon.
- Alpetragius D - (11°W 13° 8'S) A bright spot, seen by Mädler as a crater, but which as Schmidt found in 1868, no longer answers to this description.
- Anaxagoras - The centre of an important ray-system. Listed by Elger as a principal ray-system. It is also on the ALPO list of bright ray craters.
- Apollonius - Among the hills S. of this, there is a small bright streak system.
- Aristarchus - Known as the brightest crater on the entire moon's surface. Easily observable in Earthshine. A most curious fact is the antipodal location of one of the darkest craters on the moon: Tsiolkowsky! Elger listed as principal ray-system.
- Aristillus - The centre of a noteworthy system of delicate rays extending E. toward the Caucasus; and on the S. disappearing among the rays of Autolycus. They are tracable on the eastern part of Mare Imbrium near Kirch. Elger listed as a minor ray system.
- Aristoteles A - A light-surrounded crater in the Mare Frigoris, N.W. of Aristoteles.
- Atlas (bright spot east of) (unofficially called Atlas Companion by William Dembowski) (see LROC article Brush Strokes on a Lunar Canvas).
- Autolycus - Encircled by a delicate nimbus, throwing out four or five prominent rays extending toward Archimedes. Seen best under evening illumination. Elger listed as minor ray system.
B

- Bailly - N. of the centre of this great enclosure are two very distinct radiating streaks.
- Banting - unnamed craterlet with 3/4's ejecta blanket southeast of Banting. See orbital Apollo photograph.
- Beaumont - Between this and Cyrillus stand three considerable craters with nimbi.
- Bessarion - Two bright craters: the more northerly is prominently light-surrounded while its companion is less conspicuously so.
- Birt A - A light-surrounded crater.
- Blackett-Brouwer (small white spot between Blackett and Brouwer, LAC 122 in the Clementine Atlas). Looks like an oblique impact on the LRO's ACT-REACT Quick Map. There's a pile of low albedo rocks and boulders at the northwestern part of the craterlet's interior, and smooth-looking high albedo streamers on the southeastern inner slopes.

Additional Information
- North Ray and South Ray
During the last year of the Apollo program, the fifth manned lunar landing (Apollo 16's LM Orion, April 1972) took place near a couple of small bright ray-craterlets called North Ray and South Ray (north of Descartes and Dollond). Of these two, South Ray is the brighter one. The southeastern part of the North Ray's rim is the location of the so-called Big Black Boulder (House Rock), which was the largest piece of rock explored by astronauts on the moon's surface. These two small ray-craterlets are observable through common telescopes, during Full Moon. Research: Danny Caes
- A very small ray-craterlet near South Ray has been called "Baby Ray". Perhaps it is also possible to make Hi-Res webcam images of that tiny raycrater (?).
- The most beautiful lunar ray-crater
Since 2015 officially known as Pierazzo, located at 3° North/ 100° West, near crater Lents. Unfortunately its location is a bit too westward "behind" the moon's western limb ("behind" Hedin). A little bit more eastward and its ray system could have been one of the most interesting targets for telescopic lunar observers! The extraordinary ray system around this crater was captured during the Clementine mission in 1994 and the Chang'e-1 mission in 2007. See also LAC 72 in Ben Bussey's and Paul Spudis's Clementine Atlas of the Moon, and the LPOD of December 12th, 2007 (the Chang'e-1 photograph of this raycrater). Research: Danny Caes
- A tiny bright spot on the moon's near side
One of the most "compact" or "starlike" areas with unusually high albedo-value is located at 13° North/ 16° East, between Menelaus and Julius Caesar (the northwestern end of Sinus Honoris). The curious bright "starlike" appearance of this ray-craterlet is a noteworthy curiosum during telescopic observations of the Full Moon. One of the few orbital Hasselblad photographs of it is AS15-92-12548, made during the mission of Apollo 15 in the summer of 1971. Another orbital Hasselblad is AS15-93-12678, which is the only close-up of it on color film! Research: Danny Caes
- Mare Smythii's bright starlike spot
Located at 4° North/ 89° East (between craters Peek and Nunn at the northern rim of Mare Smythii) is another curious bright spot with the typical shape of a "star". This star-shaped bright spot (a tiny raycrater) was photographed during the missions of Apollo 10, 11, 15, and 17 (orbital Hasselblad and Itek photography). It would be interesting to try to observe this bright spot, and to make Hi-Res photographs of it during favourable libration at the moon's eastern limb. Research: Danny Caes

- Mare Vaporum's tiny starlike spot
Located at 14°30' North/ 0°15' West (at the western "shoreline" of Mare Vaporum) is a very tiny bright "spot" which is noticeable near the upper margin of LAC 59 (page 118) of B.Bussey's and P.Spudis's Clementine Atlas. This spot is observable through common and powerful telescopes, during Full Moon. Research: Danny Caes
- Three of Apollo 15's orbital close-up Hasselblad photographs of the area near Dorsum Gast (the western part of Mare Serenitatis) show a remarkable bright craterlet with unexpected dark "tongue" of ejected material at the southwestern rim of it, located at the southern end of that dorsum (Dorsum Gast). The exact coordinates of that curious craterlet are: 23° North/ 8°40' East.
The three Hasselblad close-ups of that curious craterlet:
AS15-81-10876
AS15-81-10881
AS15-81-10883
Research: Danny Caes
- The Chandrayaan-1 spacecraft captured an interesting example of what appears to be a fresh rayed crater on the floor of a larger crater. It is included in their photo gallery, but the location of the feature is not disclosed.
