| Duration | 1s |
| Length | 3° |
| Remarks | It looked like mostly one object at first, then stretching into a group of separate objects streaking across the sky with trails and then they started to spread a bit, like when a fireworks sparkles start to drop and separate. Two were very far behind. I could see through the window even though we were watching TV this blue-ish bright long streaking thing but seemingly very slow and we had time to all look and I went out on the deck and watched it separate and disappear behind Old Douglas Mountain. |

| Observation | Yes |
| Remarks | As described above, it looked like mostly one object and then as it continued it became 12 or so objects like the big sparks from a large firework on the 4th of July, eventually arcing downward a bit and falling slowly like firework sparks do. |
