Additional Information
- IAU page: Vallis Bohr
- The coordinates and length given in the title line are from the IAU Planetary Gazetteer. Measurements on a calibrated copy of Lunar Orbiter image IV-188H with LTVT suggest the length of the main part of the valley is 98 km. If the faint extension to the northeast is part of it, the overall length would exceed 150 km. The width of the main part varies from about 10 km in the north to 12 km in the south. The shadows indicate the northern segment is about 1250 m deep. In the 12 km wide southern segment the depth increases to something over 2700 m (since the shadows do not extend to the deepest point, the true depth could be considerably greater). - Jim Mosher
Dark halo crater near Vallis Bohr
- Unnamed bowl-shaped crater with dark (read: low albedo) halo at 90 degrees West/ 9 degrees North; immediately west of the southern part of Vallis Bohr. Take a look at the left margin of photographic chart LAC 55 (page 110) in the Clementine Atlas of the Moon (Ben Bussey/ Paul Spudis). - DannyCaes Aug 17, 2015
- Is this dark halo crater observable during very favourable libration? - DannyCaes Aug 17, 2015
- There's a small Floor Fractured Crater (FFC) immediately south of that dark halo crater, see the lower margin of Lunar Orbiter IV photograph IV-4188-h2. - DannyCaes Aug 17, 2015
Nomenclature
- Named from nearby crater (Bohr).
- This name was officially adopted in 1976. The IAU Planetary Gazetteer at one time gave the feature the same coordinates (12.4 N, 86.6 W) and essentially the same dimensions as the crater Bohr, but according to Bowker and Hughes (1971) the name refers to the valley to the southwest. - Jim Mosher
