R1: Franklin: Central peak, well terraced crater walls. Appeared to have one area of its wall that wasn't as clearly defined as the rest; perhaps due to lighting or my perception of reality.
R2: Cepheus: Smaller than Franklin and to its NW. Crater A impacted the eastern wall and is quite deep.

NOTE: These  craters are in a SW line from Atlas. Franklin had a ghost crater to its SE.
