About 7 seconds duration. We were facing West. Object started in the Southwestern sky and fell towards the Northwestern horizon. Started with red flash, like fireworks, then bright white as it crossed the sky. As bright as the moon. This was very cool to watch with my son. We couldn't believe it stayed in the sky as long as it did.

3 seconds duration. I was traveling North on Highway 191. It appeared directly over the center of my windshield. It traveled South, to the right. It was not fully dark and a very bright light streaked down and a spark of it came off the top right. Both continued down. Brighter than Venus. A spark came off the top right. Amazing it was bright considering it wasn't even dark yet.

3 seconds duration. I was facing West. Direction of travel South to North. Bright white with no sound observed as I was in closed car. Brighter and larger than a planet. Very round, quite large, and relatively slower moving than a meteor.
