I was outside in my backyard smoking a cigar and I'm always looking up at the sky star glazing. I turned NW I saw this pulsating lights. first I thought it was just a star, but I have never seen a star pulsate in such a way blue, green, red, and white. I called out to my daughter to come take look and she saw the same thing pulsating lights, told to go inside and get the binoculars and take a closer look and the object just kept on pulsating for about 20 plus minutes. we went back inside and it was still pulsating.
