[Arnold Ashcraft]

Folks:

I just uploaded two more images of the northern limb taken tonight of the nearly full moon:  CAshcraft_20090409_0153UT.jpg and CAshcraft_20090409_0153UT_annotated.jpg.  Same image actually, but the second is annotated with crater labels and the location of the north pole.  The libration is nearly +7 degrees and we don't get to see much more of the north polar region than this.  My seeing was terrible as usual which I partially compensated for by using a NIR pass filter to minimize the effects of turbulence on the image.  Those observers in better locations should try imaging tonight.  Even though the moon is near full, the northern polar region is very nicely displayed.
