The ball was larger than any meteor and it seemed slower and lasted longer than others I've seen. I listened and since there was no sound and had a blue yellow trail I just new it was some type of meteor. I've never heard of a fireball? I'm not exactly sure of the time because I was at a outdoor dinner party that started at 6:45 and we had been there for a while-at least an hour- so sighting was between 7:45-8:30ish? I was just looking into the sky when I was startled by it. My husband and friend also saw it.
