It was breathtaking. Many people around me in the crowd saw it and gasped, asking "What is that?!" It looked like it was going to hit the Space Needle from our vantage on the lawn (watching a movie) as it traversed the sky. When I saw it south of the Needle it was rimmed in green light- I wasn't sure if it was a strange firework I'd never seen before.
