Additional Information

  • Depth data from Kurt Fisher database
    • Westfall, 2000: 1.84 km
    • Viscardy, 1985: 1.8 km
    • Cherrington, 1969: 1.79 km
  • Ross and Ross D are thermal anomaly craters, implying youthful ages - Moore et al, 1980
  • TSI = 25, CPI = 10, FI = 15; MI =60 Smith and Sanchez, 1973
  • "Temporary hill", 3 km in diameter and casting a shadow, seen by Thomas A. Cragg on 16th july 1964 southeast of Ross D (source: V.A.Firsoff's The Old Moon and the New (1969), page 183).- DannyCaes May 18, 2012
  • Patrick Moore: To the northeast of Ross is Ross D, where TLP have been reported, though in my view the evidence is very slender (source: Patrick Moore's New Guide to the Moon (1976), page 249).- DannyCaes May 19, 2012
  • Possible swirl formation to the west-northwest of Ross, at 12°30' North/ 20°30' East. Page 120 (LAC 60) of the Clementine Atlas of the Moon shows something of this (possible) swirl.- DannyCaes Aug 5, 2013
  • South-southwest of Ross H', near four unnamed dome-like formations (north-northwest of the large dome Arago Alpha), is (or should be) the impact location of Ranger 6, which was an unsuccessful attempt to make close-up photographs of the moon while the probe descended toward the lunar surface.
    The exact coordinates of
    Ranger 6s impact location are: 9°24' North/ 21°30' East.
    Note that chart 35 in Antonin Rukl's Atlas of the Moon doesn't show the location of Ranger 6. According to chart 44 in the Times Atlas of the Moon, Ross H is the nearest one of the officially named lunar formations, north-northeast of the impact location of Ranger 6. Additional research Danny Caes

The field of Irregular Mare Patches (IMPs) south-southeast of Ross E (known as Ross E 1)

The exact coordinates of this IMP field are: LAT 10.460 / LON 23.547 (south-southeast of the bowl shaped crater Ross E).
