4th of July. Visitors enjoy a fireworks show, while I watched them.I was watching neighbors shoot off fireworks. Their backs were to the craft. There were 5 lights in the shape of the 5 side of a die. The object was in the northwest sky.I first thought it was a Japanese lantern, since it was the 4th of July. However, as I continued to gaze, the object didn't follow the typical Japanese lantern pattern.An interesting few things happened, as I intently watched the object. The object seemed to be watching the fireworks the neighbors were shooting off. Then in a split second, the object dropped down vertically and straight back up to its location. The brightness level stayed the same, the whole time.I went inside to grab my telescope to see it closer, when I returned, it was gone.
