I've sent the file to vk3ukf, so he can post it.

That file has been TRAPPED on a failed hard drive for 5 years. It would spin and was barely accessible with read errors and long system-wait times. It took Media Tool Professional 13 DAYS to reverse clone the 80 gig drive to a spare drive so I could then do file-recovery on the readible sectors. I apparently recovered everything I needed, including family photo scans that had been done 2 years before the drive got sick and were <duh> nowhere backed up.

I've attached most of the closest approach frames, skipping 0064 (previously posted) and two at the beginning and one at the end of this sequence where things had stopped changing fast. You can see a vague albedo feature across the nucleus at low phase, and that cleft/vally/gash across the nucleus (cut off at the bottom of the frame) in 0063. Early and late in the sequence, at high phase angles, the jets off the sun-facing lobe of the nucleus wash everything else out and increasingly obscure the nucleus, so the tail-ward lobe of the nucleus sort of materializes as the spacecraft approaches and starts to swing around to the dayside, then disappears back into the murk on flyout. (Those frames are in the animated gif but not posted here)

Hi edstrick and others the file is now online unmolested at the following URL.

The stills do not do it justice, the detail toward the end shows the shape of Halley and it reminds me of the asteroid that the japanese probe visited.

WOW. blink blink.

Thanks for making your file available ed, Kevin.

Nice! It would be interesting to do some merging of adjacent frames to improve the SNR a bit.
