Best Evidence Cases
1 cases · EQI + BAI · rubric v1.1 · 2026-06
Each case is scored on six independent evidentiary dimensions. EQI measures documentation quality — not the probability of an anomalous origin. Cases with strong behavioral anomalousness but limited instrumented capture will rank lower than their editorial tier.
February 2022 · Colorado Springs, Colorado, United States
In February 2022, a U.S. military service member reported observing an unidentified anomalous phenomenon near Colorado Springs, Colorado -- home to Peterson Space Force Base, Schriever Space Force Base, and NORAD/NORTHCOM. The witness described a "bean shaped," matte white or off-white object with an unusual surface texture. The FBI conducted a formal FD-302 interview in March 2025. An AARO Intelligence Community partner produced a separate intelligence assessment with a low-confidence conclusion. As of June 2026, AARO has designated the case unresolved.
About this ranking
EQI scores reflect documentation quality only — not anomalous significance. Cases with strong behavioral anomalousness but limited sensor capture (e.g. Levelland 1957, Coyne 1973, Falcon Lake 1967) score lower on EQI than their editorial tier. BAI (Behavioral Anomalousness Index) is a complementary 4-component score measuring kinematic anomalies, EM/physical effects, agency/awareness signals, and trans-medium behavior — independent of documentation strength. Both scores are computed from structured case data (rubric v1.1, 2026-06). Full component breakdowns are on each case's detail page under the "Scoring" tab.
