Strange objects over eastern coloradoon september 7 my friends and I were at a friends grandfathers house when we noticed some strange lights in the trees There was a very bright red orb just behind the clearing in the trees. Then there was a flsh of with light and we saw the red orb pulsate twice. It then started to rise above the trees. I was extremely frightened but I couldn't move. it then shot into the sky at an incredible burst of speeed but there was very little sound, it was almost a humming sound. Thata when we noticed that there were more than just one,we almost instantly noticed two more, then we started to look around. there was one more rising out of the tree to the south of us and one sitting above the trees almost like it was watching us,They two shot into the air to join the others in a triangular formation. The four of them then began to pulse from green to orange to red. Then from the distance we saw the others just appear out of no where. they were about a mile away but they where so bright. they to started pulsing, they did this for about twenty minutes or so and then they just seem to have vanished
