   There has been an interesting development in the world of 
the amateur satellite observers -- the first (AFAIK) detection 
of uncatalogued geosynchronous satellites and determination of 
their orbital elements.  The amateur community has for many 
years spotted and tracked classified US LEO satellites for which 
NORAD does not release elements, but the capability now seems to 
extend to GEO.  

   The amateurs' accomplishments are of continuing interest 
because, inter alia, they provide a proof of principle and lower 
bound to the capabilities other countries' space surveillance 
systems could achieve with minimum investment. 

   Here are orbital elements for two uncatalogued satellites 
found by Rainer Kracht (R.Kracht@t-online.de) in Germany during 
1995 and tracked through the present.  The GEO names and 99xxx-
series "catalogue numbers" are apparently arbitrary.  Rainer 
believes that GEO347 may be a Chalet/Vortex SIGINT satellite, 
but I don't know what leads him to this conclusion.
