The 5 bright objects were seen on the second pass between 23:38 and 23:46UTC. The faint object was not seen, though sky transparancy had decreased. These are circular orbits fitted to both passes. The orbits are likely somewhat eccentric, but with only two passes the eccentricity and argument of perigee are hard to constrain.
