Odd & Unexpected
How many UFO sightings are reported every day?
One formal UAP report filed somewhere on Earth every 35 minutes, and none of them have been confirmed extraterrestrial
Roughly 2.5 reports every hour.

What counts as a UFO/UAP report - and who actually files them?
NUFORC has collected over 100,000 UFO/UAP reports since 1974. US reports run 3,900-5,500/year; globally, 10,000-25,000+ annually. None confirmed as extraterrestrial. AARO: ~80% of investigated cases resolve as conventional objects; ~20% stay unresolved due to poor data.
Why the UAP phenomenon is a case study in how humans process unexplained evidence
The UFO/UAP phenomenon is unusual because it occupies a space where credible observations meet poor documentation and motivated interpretation. The US government's own classification of sightings is instructive: roughly 80% are resolved as conventional objects or atmospheric phenomena. The remaining ~20% are classified as "unresolved" - not because they defy physics, but because the data collected is insufficient to make a determination. That ambiguity is not evidence of anything exotic; it is evidence of the limits of human observation.
Since the US government declassified several Navy pilot videos in 2017, UAP sightings filed with NUFORC spiked dramatically. This illustrates a core epistemological problem: the reporting population is not random. People who file UAP reports are more likely to be primed to see anomalies. Congressional hearings between 2022-2024 brought testimony from retired military personnel who claimed personal knowledge of non-human spacecraft. These claims were not corroborated by any physical evidence or official investigation.
For a person interested in this topic, the most useful mental model is this: UAP reports are a real and documented phenomenon, the vast majority resolve to ordinary explanations, and the extraordinary claim - extraterrestrial craft - requires extraordinary evidence that has not yet been provided to the public. The counter above counts reports filed today. What those reports actually represent is still, genuinely, unknown for a small fraction of them.
UAP by the numbers: 15,000 reports per year, 80% resolved
NUFORC database: 100,000+ UFO/UAP reports since 1974; US-focused; 3,900-5,500 reports/year recently
US AARO: ~80% of investigated UAP cases resolved as conventional objects; ~20% remain unresolved due to data quality issues
NUFORC 2022: ~5,471 reports, highest annual total in the modern tracking period
Globally scaled estimate: ~10,000-25,000 formal UAP reports per year; ~2.5+ per hour
NASA 2023 UAP study: "there is currently no evidence that UAPs are extraterrestrial in origin"
UFO sightings vs. confirmed alien contacts, today
The gap between what people report and what science has confirmed is the most striking number in this dataset.

Annual UFO/UAP reports 2017-2024: the NUFORC dataset
The US government's 2021 UAP (Unidentified Aerial Phenomena) report and subsequent Congressional hearings normalised reporting, contributing to a 400% increase in documented sightings between 2020 and 2024 via NUFORC and official military channels, though the vast majority are attributed to known objects, drones, and atmospheric phenomena.
UAP: what 15,000 sighting reports tell us, and what they don't
From fringe to congressional hearing
UAP (the Pentagon's term for UFO, adopted to reduce stigma) transformed from a fringe topic to a congressional concern between 2017 and 2023. The release of authenticated Pentagon infrared videos in 2017 showed Navy F/A-18 pilots encountering objects with apparently extraordinary flight characteristics. This led to the creation of the DoD UAP Task Force (2020), the AARO (2022), congressional oversight hearings (2022, 2023), and NASA's independent UAP study (2023). The 2023 congressional hearing featured retired intelligence officer David Grusch claiming knowledge of government UAP crash retrieval programs, claims the DoD and AARO have denied evidence for.
What explains the unexplained?
The "unresolved" UAP cases are not necessarily unexplained, most likely have conventional explanations that investigators simply can't confirm due to poor data. Modern UAP reporting has evolved significantly: military-grade sensors capture multi-spectrum data, radar tracks trajectories, and signal intelligence can detect electronic emissions. When sufficient data exists, nearly all cases resolve. The most credible open UAP cases involve sensor data from multiple independent systems (radar + IR + visual) showing objects performing maneuvers beyond known aircraft capabilities, but even these remain officially classified as "anomalous" rather than "extraterrestrial."
Notable UAP incidents & research
| Year | Event | Reports/Value | Source |
|---|---|---|---|
| 2004 | US Navy Nimitz incident: pilots report "Tic Tac" shaped object with extraordinary flight characteristics; later declassified in 2017 | Nimitz UAP incident (2004) | NUFORC |
| 2017 | Pentagon/DoD releases Nimitz and FLIR1 videos; UAP enters mainstream discourse; NUFORC reports spike | Pentagon UAP release (2017) | NUFORC |
| 2021 | NUFORC 2021: ~3,908 reports; US DoD establishes UAP Task Force; first government UAP preliminary assessment | 4K NUFORC US reports (2021) | NUFORC |
| 2022 | NUFORC 2022: ~5,471 reports, peak; congressional hearings held; AARO established by DoD | 5K NUFORC US reports (2022) | NUFORC |
| 2023 | NUFORC 2023: ~4,881 reports; NASA UAP study released; no extraterrestrial evidence found | 5K NUFORC US reports (2023) | NUFORC |
In perspective
At ~2.5 global formal UAP reports per hour, that's 60 unexplained aerial phenomenon reports every single day, yet none confirmed as extraterrestrial in 70+ years of investigation
NUFORC's 100,000+ historical reports, stacked end to end at 1 page each, would form a pile taller than the Eiffel Tower
How the number is calculated
NUFORC receives approximately 3,900-5,500 US UAP reports per year. Adding MUFON and other registries - Global formal reports are estimated at 10,000-25,000/year. The live rate uses 15,000 global reports/year ÷ 31,557,600 seconds ≈ 0.000475/sec (or ~1 report every 35 minutes). The counter shows cumulative sightings today. Note: NUFORC reports are unverified; ~80% have conventional explanations when investigated.

Frequently asked questions
- How many UFO/UAP sightings are reported each year?
- NUFORC (US) receives approximately 3,900-5,500 reports per year. MUFON (Mutual UFO Network) receives a similar number. Globally, scaled estimates suggest 10,000-25,000+ formal UAP reports annually, not including informal social media reports. The rate is ~2.5 global formal reports per hour.
- What percentage of UAP reports remain unexplained?
- The US AARO has resolved approximately 80% of government-referred UAP cases as conventional objects (drones, weather balloons, aircraft, optical illusions, etc.). About 20% remain "unresolved" due to insufficient data quality (poor video, single-observer reports), not because they are unexplained in principle. NUFORC notes that the vast majority of reports have conventional explanations upon investigation.
- Has the number of UAP reports increased in recent years?
- Yes. NUFORC data shows a general upward trend in reports, with spikes correlated to media attention (e.g., the 2019 US military UAP video releases, congressional hearings). The rise of smartphones and better cameras has also increased the quantity of recorded sightings. The 2022 congressional UAP hearings and establishment of AARO have further encouraged reporting.
Why trust this data
NUFORC data is publicly available at nuforc.org and is the most comprehensive public UFO/UAP database in the world with 170,000+ reports dating to 1974. US government data comes from AARO (All-domain Anomaly Resolution Office), established by the National Defense Authorization Act 2022. MUFON provides independent corroboration of report volumes. All reports are self-submitted and unverified.
