Appeared as 9 satellites traveling on the same flight path 10 seconds apart

I noticed a light in the sky directly overhead that had all the characteristics of a satellite traveling approx. SW to NE. I have observed satellites in the past and at first I thought that this object was also a satellite.
Then I noticed another one traveling in what appeared to be the same flight path approx. 10 seconds after the first.  As I watched, a total of 9 objects tracked across the sky along the same path and approx. 10 seconds apart.  Because they were traveling across the sky in a type of convoy (for lack of a better term), I could see as many as 4 at one time.
Since I knew that the sun had set an hour or so earlier, I assumed that what I was seeing was sunlight reflecting off of them. This seemed to be the case since as they tracked to the northeast, they faded out. There wasn't any sound or aircraft marker lights.
I just thought I'd report it because I'm not aware of satellites traveling along the same path in organized groups.
