Interestingly enough, Cold Lake is almost exactly the same latitude, and almost exactly 160° longitude, from Moscow. Anything in a 12 hour synchronous orbit would pass very close to this station every orbit. There is some crazy hardware out there that can see space debris to about the size of your fist in LEO. The Haystack radars are listed as being able to track 1cm paint chips up to 600 miles up. Combined with what guys like Thierry Legault are able to do with 'amateur' gear I can imagine that we and everyone else has gear that can read the serial numbers off anything bigger than a breadbox in low orbit.
The TEAL program is where the NRO hides their "scopes that spy on scopes" programs. TEAL Ruby was one they didn't launch; TEAL Amber is in Maui and TEAL Blue is in Florida. I love how the Russians just post their shit online because fuck you, AFSPC. Edited to ask: That vintage of Soviet spysat was almost always in a Molniya orbit. That change things?
