Description: Elger
(IAU Directions) PALLAS.--A fine ring-plain, about 32 miles in diameter, forming with Murchison an especially beautiful telescopic object under suitable illumination. Its brilliant border, broken by gaps on the E., where it abuts on Murchison, has a bright crater on the N.W., from which, following the curvature of the wall, and just below its crest, runs a valley in an westerly direction. There is a large bright central mountain on the floor, with a smaller elevation to the S. of it, and a ridge extending from the N. wall to near the centre. On the E., a section of the border is continued in a N. direction far beyond the limits of the formation; and on the S. it is connected with a small incomplete ring; on the W. of which, near the foot of the wall, is a somewhat smaller and much duskier enclosure.

Stuart's craterlet
On November 15, 1953, the physician and amateur astronomer Dr. Leon H. Stuart took a picture of the Moon that appeared to show a flare of light about 16 km southeast of Pallas. The flare was estimated to last for about 8–10 seconds. The report was published in a 1956 issue of The Strolling Astronomer, a newsletter. However the incident was dismissed by professionals of the period as more likely a meteoroid entering the Earth's atmosphere.
Many years later Dr. Bonnie Buratti of JPL saw the photograph and decided to investigate. Assisted by a graduate student, she identified a 1.5 km. diameter crater imaged by the Clementine spacecraft. The crater has the correct size, shape, and albedo to match the expected impact energy. Some astronomers now agree that Dr. Stuart may indeed have photographed an asteroid impact on the Moon.
