Diamond over Marquette Heights, IL

The report, as filed

I was sitting in my living room at approximately 11:25pm on Tuesday, September 8th, 2015. Then through one of my living room windows, out of the corner of my eye, I saw a small cluster of green lights in the sky. They were roughly 1000 feet in the air, and approximately 1-2 miles north of my house. As soon as I directed my attention to the object, it moved towards my house but out of my viewing range. I then walked to the north window of my living room, and looked up and the object had moved to about 2-3 blocks away from my house, maintaining its same altitude. I attempted to call a couple of my friends about it as I was quite afraid, but I had no cellphone signal whatsoever. I checked out the window repeatedly for the object and it remained hovering around the same position for approximately 10-15 minutes before disappearing. I did not see it vanish, but as soon as it was gone I had cellphone signal again. No one else in my area reported anything
