Hello Malcolm,


I had the same observation as yours, and me too I was confused.  I quickly
noticed that the steady one had a slightly higher track and was about two
minutes sooner.  I found it to be travelling a bit faster than a Zenit
rocket would do so I thought this could't be the predicted object.   I did
see the Zenit rocket later on.

What we saw was Kosmos 1154(80-08A/11682).

Maybe you can simulate your observation with the elements below:

Cosmos 1154      5.0  1.5  0.0  5.4 v 20.4
