Visually tracked fast moving satellite, two other points of light converged on it from different directions at a faster rate of speed, all three stopped, momentarily, dispersed at high speed.

Iwas 24 years old at the time, at our summer cabin at Placentia Jct. Newfoundland Canada.I was watching Mizar in my telescope when I  looked up and started watching what I though was a satellite. Then I saw two points of light moving towards the "satellite "at a high rate of speed. Their speed was a lot faster then a normal satellite. All three objects stopped for a few seconds and then all three moved off in different directions.  I've never witnessed such an event before or since. I have been observing the night sky for over thirty years. This event remains to this day "unexplainable ". In my estimation, the lights were very high, perhaps close to a satellite orbit.  No sound could be heard. The lights did not flash or pulse. If someone has seen a similiar event, I'd like to hear about it.
