The circular crater below the frame's center is 25-km Koval'skiy P. Koval'skiy itself is dimmly visible to the upper right of this crater. The bright-haloed crater (south of Koval'skiy Y) near the upper left corner of the frame is not named.

If the coordinates in the caption are correct, Lunar Orbiter 3's frame LO3-037-h2 should show an area immediately northeast of Koval'skiy. It might be interesting to try to detect this area in the LRO's online ACT-REACT Quick Map.

Additional Information

The mystery of the lonely boulder track

- To the northwest of Koval'skiy is the location of an unnamed high-albedo raycraterlet (an oblique impact?), see photographic version of LAC 100 (page 200) in the Clementine Atlas (a broad white spot almost at centre of LAC 100).
- Immediately east-northeast of this bright raycraterlet is the location of a peculiar looking track south of a 20 or 25 meter sized boulder.
- The pinpoint coordinates of the boulder and its weird looking track are: Longitude 100.155 Latitude -21.045
- This peculiar appearance (the track) was independently discovered by Danny Caes via the LRO's ACT-REACT Quick Map.
- Why are there no tracks behind the other boulders in the neighborhood?
- Apollo 15's orbital Hasselblad photograph AS15-97-13181 shows a color close up of the mentioned raycraterlet (located at the southern part of Koval'skiy Y).- DannyCaes Jun 5, 2011


Named for Marian Albertovich Kowalski (1821-1884), a Russian astronomer. (Spelling changed from Koval'skij.)
