One comment: when Dennis di Cicco wrote that piece, I was still assuming
the path was farther south, and fitting my data to a flat bottomed model
(that is, the assumption was that the occultation was total). We now
know the path was farther north, and was probably just on the edge of
totality from my location. So the current fit shown at
http://www.cloudbait.com/science/pluto2007.html more accurately shows
the profile of the occultation, with the entire event dominated by the
effects of Pluto's atmosphere.

I wonder if the 2.3-m IR observatory in Laramie, Wyoming saw it. ? The MMT
got it here in southern Arizona, but to what extent I don't know - I haven't
asked!
