As expected, 03054C's matching manoeuvre is being delayed to allow it catch up to 03054A. Prior to 03054A's manoeuvre, 03054C trailed by more than one minute; reduced by tonight to 47 s. When it has closed to within about 8 s, it will perform its matching manoeuvre. At the rate of closure indicated by the present elements, that would occur early on Dec 31, +/- a couple of days.
