Hi Terry,

Regarding the close-encounter between ISS and the Russian rocket
body, I posted this to Seesat-L in the middle of June:

Cosmos 100 R/B (#1844) was the culprit.  The orbits were predicted to come
within 0.5 km of each other, with the closest approach between ISS and
C100r in those orbits at about 5 km on Sunday, June 13th at 13:31:08 UTC
