A 40 kg subsatellite was ejected from the nose of the SZ7 orbital module at
1127 UTC on Sep 27, 2008. It is probably object designated 2008-47G by the US (47C-F seem
to be the separation motor covers from the second stage, based on their
orbital parameters). On Sep 28 it was in a 329 x 338 km orbit.
The subsatellite was informally referred to as BanXing (companion satellite)
by Chinese commentators, but does not seem to have an official name.
