It is interesting to see that both launch windows today and also tomorrow's launch window are timed such that KH 11 USA 290 passes OTV 6 within 100 km on a later orbit. If OTV 6 launches at 13:14 UTC tomorrow, USA 290 will pass OTV 6 tomorrow at 22:54:50 UTC at a distance of 73 km. This is based on Marco's estimated TLEs. So Bob Christy's theory about close encounters between OTV 6 and a KH 11 appears to be correct, but it concerns another KH 11.
