AS08-13-2243; which is an orbital Hasselblad photograph made during the first manned mission of Project Apollo (Apollo 8 in december 1968), shows the sunrise terminator over the western part of Mare Nectaris, with the ruined crater Daguerre in the foreground (looking southward).
Apollo 11's orbital photographs AS11-42-6235, AS11-42-6236, AS11-42-6237, and AS11-42-6241 show the same area of Mare Nectaris as depicted in Apollo 8's low-sun orbital view in AS08-13-2243.

(IAU Directions) The Mare Nectaris, again, in the south-eastern quadrant, presents some fine examples of concentric ridges, which are seen to the best advantage when the morning sun is rising on Rosse, a prominent crater north of Fracastorius. This "sea" is evidently concave in cross-section, the central portion being considerably lower than the margin, and these ridges appear to mark the successive stages of the change of level from the coast-line to the centre. They suggest the "caving in" of the surface, similar to that observed on a frozen pond or river, where the "cat's ice" at the edge, through the sinking of the water beneath, is rent and tilted to a greater or less degree.
