Note: In some of the photos the witness zoomed in on the orb with his camera. A check or winds aloft and surface winds showed that winds were from the Southeast at the surface and were from the South to Southeast up to about 4,500 feet where they veered to the West. Winds were quite light at these levels. Winds were from the West at 7,500 feet and increased to about 30 MPH at 15,000 feet. Given this information the object was not drifting with the wind if it was at around 7,500 feet as indicated by radar and an object drifting with the wind would not have made a sharp turn with an abrupt change in velocity. The object WAS NOT A WEATHER BALLOON. The weather balloon (00:00 GMT run) would not have been launched until 6 PM MDT. This object was sighted only a few miles from Denver Airport and would have been located in controlled airspace. Class B airspace (closest to the airport) is from the surface to 12,000 feet within 10 nautical miles of Denver Airport. Radar shows that the object was in this area. Unfortunately the witness has not responded to follow-up questions so some assumptions have been made in this analysis. (For example it was assumed that the object was near an angle of 45 degrees above the horizon.)
Update – Dec 22, 2013 – Photo Analysis by David Mason: I examined the photos and the one thing I can add is that the depth of field confirms it to be a distant object relative to the tree branches. You can see from the various photos when the object is in near focus the branches are out of focus, and when the branches are focused the object is blurred. This does not seem like a hoax as the photos don’t appear to be staged. The object also lacks definition wherein most hoaxes seem to show inexplicable detail. We can’t call it a genuine UFO, but it can’t be explained at this point.
