I was laying on my balcony watching the stars around 1am there were virtually no clouds and the sky was very visible. A bright greenish blue sphere shot across the sky for not even a quarter of a second then disappeared it was way to big to be a shooting star and to fast also. As soon as i realized what i saw i got up to see if it was somewhere else or what happened. Also at the very time it happened my dog jumped up while she was laying next to me and watched the sky. She was very upset with her hair sticking on end for about a minute. She watched the area it was at for a while after it disappeared.
