Emily posted a very nice article in her blog on the SMART-1 lunar impact in September this year. Here's a map of the targeted point:
But as Emily explained, the actual point may be off because of uncertainties about topography. I'm starting this thread to have a place for news and opinions on it, and - I really hope - maybe some observations at the time from any amateur astronomers out there. This event will be the last event to make it into my atlas. I've left a space for it, and I will make the final maps and fit them in, and then send the stuff off to the publisher.

Here is a side by side comparison of an area immediately to the west of the SMART-1 impact point (west of it because the Clementine image doesn't cross the impact site itself).
I'm comparing Lunar Orbiter 4 - the new USGS digital version - with Clementine long-wavelength infrared (LWIR) and AMIE. Warning - this is not a fair comparison for AMIE because it's not raw data. This is just cropped out of the big mosaic of the landing area recently posted. This shows LO4 and Clem at full resolution. The AMIE image is enlarged to match the scale, hence its fuzziness. It is possible that raw AMIE images would equal the resolution of the other two, or get fairly close, near the periapsis latitude. A few other points can be made - the lighting is reversed from Lunar Orbiter, so areas lost in shadow in Orbiter will be seen in AMIE and vice versa - especially important near the poles. And Orbiter coverage of the farside is inferior to this nearside area, so AMIE will at least equal it in many areas. And the Clem LWIR is only available in narrow strips. So we benefit most by having access to all three types of image. AMIE apparently took 20,000 images. When they are released - and especially if good global mosaics are constructed - they will be a very useful addition to lunar databases. And let's not forget that, although several other orbiters are planned, we don't know how many will actually fly successfully.
