This unclassified briefing from the All-Domain Anomaly Resolution Office was given by Deputy Director Tim Phillips to the Defense Space, Geospatial and Intelligence Leadership Conference and was released on 2/6/2025. It defines UAP and notes that most reports lack enough data, while most that can be assessed resolve to mundane objects. It says a 2018 Mt. Etna object was likely a balloon. It also describes controlled tests at Camp Grafton, North Dakota, a Space UAP Tiger Team, and Starlink flaring as a cause of reported orbs.

MT. ETNA OBJECT

▪ Event: In 2018, a US UAS platform captured video of an unidentified
object while observing an eruption of Mt. Etna in Italy. The object
appeared to pass through the volcano's plume without any impact on its
performance, altitude, or trajectory.
▪ Findings: AARO, in coordination with IC and S&T partners, assesses with
moderate confidence that the object was a balloon drifting with the wind
approximately 170 kilometers from the volcano.
▪ Analytic Factors: AARO’s IC partner employed full-motion video analysis
software, 3D modeling, and pixel examination to assess the object’s
performance characteristics. AARO also applied novel speed and
distance calculation techniques to determine the object’s location.
▪ AARO estimated the distance between the UAP and the UAS using
weather analysis of the cloud deck and wind speeds.
▪ AARO found that the object's flight path did not intersect with the ash
plume by analyzing pixel luminosity against its surroundings.
