The brightness and structure I saw was all new to me. Very memorable event. Please let me know how far away and at what altitude this object was. Can you estimate a size and speed? Any idea what the source of this may have been? Thanks! Brad

Remarks
Train of gradually smaller somewhat separate white light balls left behind moving bright white 'head'. They seemed slower and glowed out quickly. I only saw a short movie of the trajectory before the head disappeared over a hill which was at a higher elevation than where I was.

Remarks
I saw uneven gaps between train of light balls. About 6-10 balls. Linearly decreasing in brightness and the farthest balls seemed blended together compared to the balls immediately behind the head.The last one closest to the head had bigger gaps in front and behind it than the others. They all faded out like fireworks.
