Ulhas, 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 star(s).
