    The only pair I found within +-3 min and 15 deg was two Cosmos 2251
    collision pieces, 15' apart AND 50s in time, AND traveling NNW-SSE.
    If separation was 10' or more it could be the wing tips of a high aircraft.
    NOSS pairs are separated by about 4 degrees (or more), but there are
    science satellites very close.
    
    In observations reports UTC time should be used (I assumed you are at
    UTC-6), and time and position accuracy and a magnitude estimate, and one
    position between a recognizable star pair and the direction it crosses the
    line would be helpful, complemented by the speed (time to pass your
    binocular FOV), or another position and the time to reach that.
