    You saw the NOSS 2-2 triad, a known formation of three U.S. satellites. NOSS
    stands for Naval Ocean Surveillance System, which consists of several satellite
    formations, each having two or three satellites in close proximity to one
    another. Normally these satellites are relatively dim to the unaided eye, but on
    occasion they brighten sufficiently to be easily seen in a dark sky. 
    
    Here is the Heavens-Above prediction of the pass you observed:
