  • Apollonius N, the 9th item in C.A.Wood's list of Concentric Craters (1978), is noticeable on the Hi-Res scan of Lunar Orbiter 4's photograph LOIV-184-h1. Because of the oblique look at it (at the region of Apollonius and Apollonius N) it's rather difficult to locate both of them. But... once you have detected the dark-floored Firmicus, it will be an easy task to discover Apollonius N. In this online scan of LOIV-184-h1, we are looking "upside down" at the Apollonius region (north toward the bottom). The Concentric Crater Apollonius N is "just above" the dark-floored Firmicus (in reality it's SOUTH of Firmicus).
  • Concentric Crater Apollonius N was also captured on Apollo 17's orbital ITEK-panoramic frame AS17-P-2914 (scroll all the way toward the frame's right margin, and you'll see it).
  • It (CC Apollonius N) is also noticeable on the oblique southward looking ITEK frame AS17-P-2595.
  • The remarkable "flower"-like appearance of CC Apollonius N (during high solar illumination) is noticeable on Apollo 17's ITEK frames AS17-P-9440 and AS17-P-9445.
