Hello friends,

The Arizona folks are posting raw data over here:
http://www.lpl.arizona.edu/~kholso/data.htm

no sign of a meet&greet - yet.


The NASAtv relay through the web has been holding up all day,
and the AMC-6 signal is on transponder 9 for any other BUD enthusiasts 
out there.

A happy day for the species.


Cheers,

Bret Kulakovich
