At the time of culmination of your observation (22:30:48UTC on the 2nd of
December); 

and using:

1 27556U 02052A   02336.87613426  .00013720  00000-0  19050-3 0   335
2 27556  51.6321 285.9871 0005671 239.0873 196.7245 15.57320542  1353
and;
1 25544U 98067A   02336.18166133  .00140171  00000-0  19004-2 0  4314
2 25544  51.6360 289.4670 0003111 225.9823 275.3484 15.56678595230179

I estimate that the angular separation from your viewpoint was just under four
degrees and the angle of elevation of the pair was just over 66°.

The physical separation distance was 11,478 metres (7.13miles), with the
Orbiter trailing behind and about 540 metres above the Space Station.
