Additional Information

West-southwest of Nunn, at 4° North/ 89° East (between Nunn and Peek) is a craterlet with remarkable bright "star"-shaped ejectablanket, which could be an interesting target for today's observers and photographers of the moon's eastern limb. This little bright spot was photographed during the missions of Apollo 10 (AS10-33-4886, AS10-34-5081), Apollo 11 (AS11-42-6295 + 6296, AS11-43-6452), and Apollo 17 (AS17-P-2573, 2578, 2580, 9108).

  • Named for Joseph Nunn (1905–1968), an American engineer. In 1956 he worked in collaboration with Dr. James G. Baker to design and manufacture a series of satellite tracking cameras. These were called Baker-Nunn cameras after their designers, and consisted of a very precise tracking system combined with an unusually large, wide-field camera for photographing large areas of the sky. Joseph Nunn was responsible for designing the mechanical elements of these cameras, while Dr. Baker worked on the camera. This camera provided tracking data on the Soviet Union's Sputnik I satellite.
  • This name was introduced on LTO-64D1 (for which it served as the chart title, and on which it is listed as "approved by the IAU"). It does not appear to have replaced a previous name for this feature. Although Nunn appears in the cumulative list of approved names in IAU Transactions XVB, it is not clear precisely when and where it was approved. - Jim Mosher
