On 3-19-19 I looked up into the night sky from my kitchen window (facing east at 11:30 pm CST) and noticed a solitary star.  (I had just let my dogs out in the backyard to go to the bathroom.)  The "star" was high in the sky, approximately 60 degrees or so from the horizon.
The "star" then began to move.  It's movement is best described as squirmy and its form was constantly changing.  Small points of light dispersed from it, remaining very close and then it would all fuse back together.  It was "ever changing" in a constant state of flux.
The "star" moved to the right and upward over the course of 2-3 minutes.  It covered a distance approx. twice the size of my double garage.  The garage is approx. 40-60 feet from my kitchen window.
Soon after a light haze of clouds covered the sky and the "star" disappeared.
