We noticed this light out a few days ago and saw it again. i used my binoculars and could not believe it.. shadows would take the image shapes, looked like a round spot light on it showing a gas like picture design and a line through it that went from one end to the other slowly. crazy part was when looking like a dirty cloud in a clear ballon but darker undefined bloches were moving around inside like patches or microbes. under a microscope. eventually went further way then disappeared after a few hours.
