It was so surprising. I have never seen anything like it. I was watching tv when the moving light caught my eye. It looked so close I thought I would hear a sonic disruption. I was inside and did not hear anything.

It appeared to look like a firework but it was too large and brighter. The trail was white. It simply disappeared below the horizon.
