    It is indeed difficult to tell anything without seeing the photographs.
    But I think those must be star-trails for following reasons:
    - it is very rare to have two *bright* satellites moving side-by-side
      very close to each other, at the same speed. (You mention that the
      trails are of same size, which imply that the satellites were moving
      at the same speed).
    - The sky map show that the moon was in Taurus that time and there are
      a few stars there bright enough for a 1 second exposure.
    If I could get to see the photograph I can verify it for any possible
