13 June, 2015 just after 9:00 PM driving NORTH on ROUTE 15 after leaving "Snow's Corner" gas station in Orrington, Maine. 100 to 200 yards from my turn off to the right, just before the Orrington-Brewer town-line, I saw a bright teal object slightly above the trees to the North-Northeast going slightly above the tree tops, then dipping below with some lateral motion back and forth as it did. It was "triangular" but had a round shape with smaller circles underneath. It illuminated a teal color (not unlike the background of this text field) seemingly from within as the surface "glowed" teal, with black features on it. At one point it tipped slightly away and I could see the bottom of the object. Lastly, it went below the trees one last time and I did not see it again. This sighting lasted less than one minute, but more probably less than 30 seconds. I pulled over in my truck and tried to see it from the next road down from mine but could not. I then parked my truck and went inside to grab my 10x50 magnification binoculars and ran back to route 15 and walked down to the train-tracks that go across route 15 in Brewer, paralleling the river - but the object was no longer visible. I though I might find some people outside using a drone of some sort, but there was no one outside that I saw. There was also no differentiation in color scheme of the lights to indicate a bow/stern or port/starboard configuration for night flying. At this time I called a family member to tell them what I'd seen and the call was made at 9:28 PM per the phone's history. [NOTE]: My father has been a turbo-prop pilot for 40+ years and I have been flying as long as I can remember (I am 26). We live just south of Bangor International Airport's 330 Final Approach. BIA is an active Air National Guard base and we consistently see: KC-135's and C-17's. More rarely, but occasionally, F-16's, F-18's, A-10's, as well as British Typhoons and Tornados. Eastern Maine Medical Center is also a few miles upriver with a Life Flight Helicopter and pad, so we see these quite frequently as well. This object was clearly not a conventional aircraft and moved very quickly back-and-forth and up-and-down. The color was almost as bizarre as the behavior itself. [PICTURE]: It repeated the "1" > "2" steps several times, and the "3" > "4" was it disappearing out of view and below the tree line in that direction.
