Triangular flying object moving to the side.

I was getting home around 1 am, and noticed what I thought was a plane with its landing lights on. It seemed strange though since it was pretty high up. When I got out of my car I noticed that it wasn't moving in the direction that a plane would if it was using its lights. It was also really high up, and there were no clouds in the sky for the light to be reflecting off of. I tried to take a video with snapchat, but you couldn't see it. I was able to get this picture from my phone's camera. I didn't stay outside to see what it did after the picture was taken. The object was moving down and slightly to the left relative to the picture.
