An airborne object over Cheyenne Mountain, Colorado

According to the accounts of five U.S. Army service members On 15 February 2022, an airborne object was observed approximately 6 miles to the west over and slightly behind the Cheyenne Mountain silhouette for approximately 30 - 180 seconds. The witnesses describe the object as roughly the size of a large jet and resembling an angular, non-symmetrical potato made of uneven panels, which was completely stationary about 300-500 feet above Cheyanne Mountain while slowly changing shape. It had a slightly translucent, shimmering white appearance, with defined edges and a milky shimmer that reflected sunlight. The witnesses noted that the sky was clear, and despite keeping their eyes on the object, it suddenly disappeared.

At 0945 MST on February 15, 2022, in Colorado Springs, the sun was positioned at an altitude of about 27.5 over the horizon in the southeast sky and roughly at an azimuth of 125, casting shadows toward the northwest and providing soft, angled light. According to the National Water and Climate Center reporting, snow depth on Cheyenne Mountain likely ranged from 6 to 12 inches. Although witnesses reported clear, blue skies, multiple weather reports, including those from AFWA and Weather Underground, indicated the presence of clouds, suggesting that the skies were partly to mostly cloudy that morning.

Analysis possibly indicates that the positioning of the sun in relation to Cheyenne Mountain would allow for backscattering of sunlight reflecting off snow-covered ground. This reflection could illuminate low-level clouds in the vicinity, which might account for the visibility of the object followed by its sudden disappearance. It is possible that either the clouds or the sun shifted slightly, causing the reflection to vanish. has low confidence in this assessment based on uncertainty in the field of view of each witness, and exact level of cloud cover.

Analyst Note: Altostratus clouds are a kind of mid-level cloud known for their consistent gray or blue-gray appearance. These clouds usually develop at altitudes ranging from 6,500 to 23,000

/feet (about 2,000 to 7,000 meters) and can create a dense, uniform /layer across the sky or thin and wispy. While they often appear /opaque, altostratus clouds can permit some sunlight to pass

/through, resulting in a luminous effect. Typically, the presence of /altostratus clouds suggests that precipitation is imminent, as they

/may bring light rain or snow.

Analyst Note: Backscattering is the phenomenon where sunlight reflects off the snow-covered ground and reflects upwards, scattering through the atmosphere and illuminate low-level clouds. This is especially noticeable when the sun is low over the horizon. No aircraft or balloons were noted active in or around Cheyenne Mountain during the time the witnesses saw the airborne object.
