Fran,
The two images I referenced are representative of the highest
resolution available from LRO at 0.5 m/pixel. They were
taken during the 50 km mapping orbit. We briefly did an
equatorial dipping orbit that brought us down to as low as 20 km
for the purpose of imaging the Apollo landing sites and other
areas of interest but I don't think we imaged your target.
Due to limited propellent we have since moved into a low-cost
eliptical orbit where over that latitude the spacecraft is
roughly 100 km above the surface, so any future imaging there
will be lower resolution. Note that while there are
limited areas for which Lunar Orbiter resolution is higher than
LRO one should also consider other factors for image quality,
such as dynamic range, linearity, etc.
Regards,
John

John,
Looks like the shadows are really OK on these images but
nowhere near the res of the Lunar Orbiter in 1966. I assume
that the ones on the web are made that way on purpose for
dloading. Is there any way we can get a much higher res image
of that area?

LROC NAC imaging is somewhat opportunistic so when the
conditions are right the image is taken, providing that some
other target does not take precedence.
