Observed OAO 2 r/b (03598) and Cosmos 304 r/b (04139) on 8/3/04 from Tulsa. They appeared to "collide" to the naked eye - I estimate now after the shock they were actually 1/2 degree apart at closest approach at 02:54:54 UT. I was shocked because both were unids to me at the time - although they were both easily seen naked eye. I had been following 03598 for 45 seconds when 04139 approached from the north. What a spectacle! Later identified them using FindSat. Now for the question: I know they were miles apart but haven't found a good (read: easy) way to calculate their range at that moment.
