Enter a place, date, and time. AnomalyBrief checks weather, visibility, solar activity, sky events, and public source records — then builds a research trail you can share or export.
Plus 50 reference cases used to demonstrate the cross-check workflow. PURSUE count reflects the live war.gov/ufo mirror; refreshes daily.
Enter a location and date. Get weather, cloud cover, solar activity, and geomagnetic context — the full sky picture for any anomaly report.
Browse UAP records, sensor reports, and declassified documents with documentation scoring and direct source links.
Research briefs built from real cases with source trails, context checks, open questions, and shareable links.
AnomalyBrief connects public anomaly reports to primary sources, cross-checks signals against independent data layers, and assigns a structured evidence score. Every claim links to an origin document.
Every case links to its original public source. No orphaned claims. No mystery citations. If it is in the database, there is a document or official record to point to.
Each signal is cross-checked against weather data, aircraft transponder records, satellite pass predictions, and optical artifact catalogs before a case is published.
Our 0–100 score measures research completeness — how much verifiable data supports the case record — not the probability of any particular explanation, including extraterrestrial origin.
Enter coordinates, city, date, and time. AnomalyBrief checks public weather and space-weather data to show what the environment looked like during a reported event.
Before a case enters the database, we run five parallel checks against independent data sources to identify conventional explanations and flag what remains unresolved.
NOAA surface observations, radiosonde balloon logs, and inversion layer data.
ActiveAstronomical event catalogs, transient alerts, and sky condition archives.
ActiveCelestrak TLE pass predictions cross-checked against reported time and bearing.
ActiveADS-B transponder data and FAA NOTAM records for the reported location and window.
ActiveJPL Horizons ephemeris, fireball catalogs, and variable star indexes.
ActiveThirty public and official data sources across eight categories. All free, open, or government-published. No scraping, no proprietary feeds, no speculation dressed up as data.
Verified public records and reference cases — searchable by location, agency, evidence type, or any keyword. PURSUE-derived records are clearly tagged.
