In the excitement of catching four objects I missed the 5th object, as
well as a much fainter 6th object.

The 5th object [99571/20712E] was equally bright and steady as the
other 4, while the 6th object [99572/20712F] as much fainter (~8th
magnitude). The 5th object has a similar orbit as the previous 4,
while 99572/20712F appears to have an inclination of a degree
higher. Perhaps this is debris that was ejected during separation?

Based on the similar brightness of objects A, B, C, D and E, it is
unclear which are the payloads and which is the upper stage.
