While driving home from work 10/13/15, I saw what appeared to be two red and one green bright lights connected to something larger, hoovering at treeline in a residential are near a main road. I parked in a parking lot and watched it for approx 1 hour while I talked to my mom. At first I thought they were connected to a tall tower that I had maybe never noticed before, but after just appearing stationary while flashing two red lights followed by one bright green flash for about 15 it began to slowly descend then ascend as well as move side to side. I was so glued to the light show that I didn't think to hang up from my mom and film it with my phone. After watching for approximately an hour I decided to go home and check online to see if anyone was reporting this and found nothing. There were many cars driving on the main road pass it. I thought others must be seeing this because lights were unusually bright.
