The 2023 Western United States UAP Event: Analysis of AARO Unresolved Case D077

Incident Overview

In October 2023, a series of anomalous sightings occurred over a two-day period near a sensitive national security installation in the western United States. Six federal law enforcement special agents reported observing unidentified aerial phenomena, specifically described as orange and red 'orbs.' The agents noted that these objects exhibited loitering behavior and, in some instances, appeared to 'launch' smaller red orbs. The duration of these sightings, which lasted for several hours, presented a significant challenge to conventional explanations regarding drone or aircraft endurance.

AARO Investigation and Findings

The All-domain Anomaly Resolution Office (AARO) conducted a comprehensive review of the incident, cross-referencing agent testimony with radar data, ADS-B logs, and military flight records. In a memorandum dated June 5, 2026, AARO addressed several hypotheses. While approximately 60 percent of the activity was attributed to military aircraft deploying infrared countermeasure flares—a conclusion supported by historical flight logs—the remaining 40 percent of the observations could not be reconciled with known military or commercial capabilities. Specifically, the stationary nature of the red orbs for several hours was deemed physically incompatible with the burn-time and descent rates of standard military flares. Furthermore, AARO's search for 'Blue Force' (U.S. developmental) programs that might account for the phenomena yielded no matches. Consequently, the case remains classified as unresolved, highlighting the ongoing challenges in identifying anomalous aerial activity near restricted airspace. The full documentation of this analysis is available through the AARO archives.
