Sometime around 11:30pm I walked outside to get something out of my vehicle. As I left the vehicle, turning 90 degrees, I observed two faint lights just above the tree line in my backyard. I stood, and observed said lights for around 4 minutes. During this time the lights, which were two side by side horizontally, went from being extremely dim to being very, very bright, as well as remaining motionless for the entire sighting. I know this to be true due to where they were positioned between the tops of two tall pine trees. After the light became powerfully bright I ran inside to get my phone, so that I could document what I was witnessing. I retrieved the phone, and upon returning it had changed from two bright lights to three bright lights, and still in a motionless, horizontal, linear fashion. I attempted to record the event, turned the camera on, and pointed it at the lights. While I was viewing the lights on the screen, and attempting to press record they simply vanished, as in, they were there one second, and then they were not.
