Tony, I am very interested in imaging Titan's shadow transits. I put together a similar table as yours a few months back, and the times match up for the most part. I used the excellent WinJupos freeware for calculating the times. What was the software or Web site that you used? Here's my summary on Cloudynights. http://tinyurl.com/5qh39b By the way, the seeing forecast for this morning on the Clear Sky Clock site showed "5 out of 5", but it was between 3 and 4 in my back yard. The CSC forecasts are able to predict poor seeing (when you're below a turbulent upper atmosphere), but can't capture local effects. I have seen 5/5 seeing in my back yard at times, by the way.
