Long string of a line of stellar type objects moving from SSW to NNE.

I am a seasoned amateur astronomer. Went out to look at the night sky to check out my new eyeglasses. Looked upward toward the zenith near the north. Movement of "stars" caught my eye. Then I saw more moving points of light. First thought was a satellite array moving together; then it became evident that there were scores of objects (maybe 20-30) following in a straight line moving from SSW to NNE through tail of Ursa Major. I would estimate the brightness of the points of light to be -2 magnitude. All followed the same path. Spacing was not uniform. No noise. They flickered out before reaching the horizon (possibly passing through the earths shadow terminator.
 Might have been multiple deployments of satellites.
