Eric, Phil, thank you very much--high praise indeed from two very skilled observers. 
We've had an amazingly long stretch of clear weather here and not wanting to waste it, I got up again to make one last observation of W1 Boattini. At 0820 UT (4:20 AM local), the Moon was still 55 minutes from setting and the comet could just barely be seen at an altitude of 29° as a faint smudge next to 8.0 magnitude star TYC651-258-1 (the star was right at the threshold of visibilty in the moonlight, too). By 0840 UT, Luna had dropped low enough to allow a better look at the coma and central condensation, although this comet is best seen in dark skies. It remains fairly large and bright given the conditions. I updated my sketch with the comet's new position. It may be traveling closer to 35 minutes of arc in 24 hours rather than 30 minutes.
[Edit: I added details to the original sketch from my observing notes for each subsequent observation.]
