Jim, if my image was taken later, why are the shadows in it longer than those in Larry's image (waxing moon)? Also, three hours between? How could this be? I noticed major changes in the illuminated area of the peaks beyond the terminator in just 1/2 hour-- yet they appear essentially the same in both of these images--within a few minutes not hours. It seems to me that 3 hours of difference would certainly make a much more dramatic difference in comparative illumination. My image corresponds to about 18:15 NZ local for Dunedin (-7 UT for me, +12 for Larry) according to the Virtual Moon ephemeris (illumination 87.1%, colong 43, solar incl 1.5, phase 42.2). So i'd be guessing Larry's image was taken just a few minutes after that time. So Larry, what time were you imaging Gassendi? (Curious minds and all that... )
