R1: Hipparchus had a smooth floor except for what appears to be two ghost craters plus craters N and X. Crater N was central on the floor whereas crater X looks to have impacted the wall. C1: I referred to the two buried craters as ghost craters (refer to R1) NOTE: Also identified Pickering outside the wall near Horrocks. |
