    From my location in Central Germany I had the very same impression looking 
    through 10x50 binoculars between 15:59 and 16:02 UTC (28-NOV-08). I likewise 
    had a somewhat cloudy sky. One orbit later the clouds had thickened but I was 
    able to pick out the ISS and Shuttle as fuzzy dots through the clouds during 
    the final 15 seconds or so before shadow ingress at 17:34:55 UTC. The weaker 
    spot which I take to have been Endeavour was leading by about 3 degrees or 
    more which I find quite a lot if the separation burn was just half an hour 
    earlier. But maybe I was just fooled by the cloudy conditions which prevented 
    me from taking correct timing and angle measurements (there is nothing to be 
    seen on the picture I took).
