I was looking toward the northwest sky when I noticed two distinct, very bright lights that were at about 20º in the sky and maybe 25 miles or more away, As I observed the lights it seemed that they were a part of one extremely large unit which was massive in distance from one another (which was not visible to me). I was wearing an LED headlamp, which was on, and I decided to see if these lights in the sky were maybe some sort of vehicle that was aware of me watch the lights so I waved my hand across my headlamp in short and long passes a few times. I then saw the light turn off and on I a matching pattern. After about 10 minutes I watched the light compared to the surrounding sky of know aircraft that were flying over the northwest sky which lead me to believe that the lights I was looking at were not moving in any direction. Then the lights started to turn off and on in an alternating pattern without rhyme or reason and appeared to have many smaller colored lights underneath the other two main light which gave a shape of the bottom of a flattish bowl. At that point I believe I was looking at a UFO. Amazed I continued to watch the light as I thought about going inside and getting my phone to take photos, but I decided not too for fear of not seeing the lights again. After watch seem like 20 minutes the lights turn off for a few seconds then back on and then appeared to move away from it's location towards the NW sky in an extremely fast yet smooth arch and disappeared from view.
