From this article the Berthoud Ufo lights
On Thursday April 7, 2011 my night astronomy class traveled to a dark sky site on CR 10 two miles north of Berthoud High School. We had a 16 inch telescope, 10 Celestron Binoculars, and a Cannon 450 with a 200mm lens and tripod. We were all set for a night of observing and astrophotography when those "strange lights" appeared. This time we had a clear view of the eastern horizon and could watch these lights interact with each other. At times they would remain stationary in a triangular formation and then they would approach each other. The strangest event was when one light hovered above another and shot what appeared to be a beam of very bright white light to the lower object. We watched these lights from 8:00 until 9:30 pm and then called it a night. I captured at least 18 images with my 200mm lens and posted a few below.

There is a picture of the sequence that is not here called Lights G Berthoud.jpg where you can see how one of those lights going to be very intense to a sequence of points. This indicates that it could be planes. Is there an airport near the area? After reviewing the photo G, my opinion now is that these are aircraft lights. The difference between flashing points and fixed lights is the angle at which the plane is photographed.
