Circle shape turned triangle (T) shape produced bright color in night sky then disappeared.I walked outside on my front porch to let my 3 dogs out, my sister was with me and we had thought it was the north star until we looked up further in the sky and saw the actual north star. I continued to watch while my sister went for the brand new sony dcr-sx45 handycam. Then I started to film and use the 70x zoom, It was then that we realized what we were witnessing a ufo, our first sighting. It was a circle almost plate like and continued to more almost like spinning in place. To the naked eye you could not see the movement but it continued to spin and dark back and forth, getting closer and further from us with-in the blink of an eye. Then it started to change color producing a dark but bright purple light, almost like a small flash. Then it changed into what at first seemed like a cross and then a triangle, at the end of the recording u can see it almost like wings flapping and within a blink it disappeared.
