Hi All

Last night I came across a mysterious emission on ~2251.0MHz. After 
studying it for awhile it was clear it was in a geostationary orbit at 
about 146W.  The modulation of the satellite's signal appears similar to 
Chinese missions I have seen in the past.  No obvious clue for the 
origin of this emission as this area of sky is void of many emitters.  
An observer in California just confirmed the emission.

I tried visual observations last night but was foiled by the bright 
Moon.  Wondering if anyone out there can help track down this emitter 
visually?

This TLE very roughly describes it's position.
