  • Monira (on the northeastern part of the floor of Alphonsus).
  • Müller
  • Oppolzer
  • Oppolzer A (see also the Lunar Heliotrope project, aka Project Pharos) (a large sunlight reflecting mirror on top of an unmanned rover to create a lighthouse effect and to observe the minute speck of light through very powerful telescopes).

To give names to all these radial "grooves" would be a most interesting project!).
