Poster presented at the 42nd Lunar and Planetary Science Conference by N. G. Moss, T. M. Harper, M. B. Motta, A. D. Epps

"While some candidate craters were observed that appeared in LROC data but not in Lunar Orbiter data, these were all very near the edge of discernable feature size and are almost certainly explained by various differences between the images (e.g. sun angle or viewing geometry). While our initial search did not find any discernable new cratering, we have shown that data from the original analog Lunar Orbiter tapes, as recovered by the Lunar Orbiter Image Recovery project, possesses the characteristics necessary to discern new craters at reasonably small sizes. If the entire Lunar Orbiter data set was recovered in this manner it may be possible for future researchers to apply automated methods to detect changes with much better chances of success."

CC How about putting an X on the map where you saw it? LMP I keep looking for -- yes, we will. I was planning on looking for those kind of things....
