What's documented: Official counts from the Air Force's Project Blue Book (1947 to 1969), the Director of National Intelligence (2021 and 2022) and the Pentagon's All-domain Anomaly Resolution Office, or AARO (2023 to 2025). Every one is linked below.
What's claimed: That the unexplained share proves something non-human is out there. None of these reports says that. AARO's 2024 report says it "has discovered no evidence of extraterrestrial beings, activity, or technology."
Status: Open. Most reports get explained once there's enough data. A small number stay unexplained in every era, and they're mostly cases with too little information to judge.
Last checked: November 10, 2026, against the government reports linked in Sources. AARO's reports page still lists the FY2025 report as its newest annual report.
How many UFO sightings are reported?
It depends on who's counting. The only counts that come with an official answer about what was explained are the government's, so that's where this page starts. Here's every public tally we could find, in order.
| Period | Who counted | Reports | What happened to them |
|---|---|---|---|
| 1947 to 1969 | U.S. Air Force, Project Blue Book | 12,618 sightings | 701 left "Unidentified" (about 5.6%) |
| 2004 to 2021 | Director of National Intelligence, preliminary assessment | 144 reports from government sources | 1 identified with high confidence, a large deflating balloon |
| Through Aug. 30, 2022 | Director of National Intelligence, 2022 annual report | 366 new reports, 510 total | 195 given an initial label (163 balloon or balloon-like, 26 drone or drone-like, 6 clutter); 171 uncharacterized |
| Aug. 31, 2022 to Apr. 30, 2023 | Pentagon and DNI, FY2023 report | 291 reports | The report expects most to turn out ordinary once studied |
| May 1, 2023 to June 1, 2024 | AARO, FY2024 report | 757 reports (1,652 total by Oct. 24, 2024) | 292 resolved or recommended for closure; 21 flagged for further analysis; 444 to the active archive |
| June 2, 2024 to May 30, 2025 | AARO, FY2025 report | 319 reports (1,870 total) | 114 resolved; 9 flagged for further analysis; 191 to the active archive |
Two cautions about that table. First, the government periods don't line up neatly, and each report also sweeps in older reports that hadn't been counted before. The FY2024 report's 757, for example, includes 272 reports of events from 2021 and 2022 that only reached AARO that year, many of them pilot reports from the Federal Aviation Administration. Second, Blue Book counted public sightings. The modern reports mostly count reports from military crews, military sensors and airline pilots. They aren't measuring the same thing.
The jump from 144 to more than 1,800 reports doesn't mean the sky got busier. It means Congress required a reporting channel and the military started using it. We cover that shift in are UAP sightings declining?
How many UFO sightings are explained?
Across the modern reports, the honest answer is "about a third so far, and most of the rest can't be judged."
- FY2024: AARO resolved 49 cases during the period and had another 243 recommended for closure by June 1, 2024. Its summary counts the same 292 cases a slightly different way, as 118 resolved plus 174 queued for closure, and says all 174 were finalized as ordinary objects by publication. That's 292 of 757, or about 39%. It placed 444 (about 59%) in the active archive and flagged 21 (under 3%) as worth more study.
- FY2025: AARO resolved 114 of the 319 new reports, about 36%, and recommended closing three more. It also resolved 256 cases left over from earlier periods, for 370 resolved in the year. It moved 191 (about 60%) to the active archive and flagged 9 (under 3%) for more analysis.
- Blue Book: The Air Force's 1985 fact sheet, posted by the National Archives, says 701 of 12,618 sightings stayed "Unidentified." That's roughly 94% explained, though by the Air Force's standards of the day. Our Project Blue Book briefing covers how the Air Force reached those labels.
The 2022 report is the one most often misquoted. Its 195 "characterized" cases were initial labels, and the report says plainly that this doesn't mean they were positively resolved.
What do explained UFO sightings turn out to be?
Ordinary things, every time so far. AARO's FY2025 report says all of its resolved cases were "prosaic objects such as balloons, satellites, birds, aircraft, and unmanned aerial systems," plus one commercial rocket launch and one person flying a jet pack.
Satellites are the fastest-growing explanation. AARO says a new modeling capability let it resolve 238 reports as satellite flaring in FY2025. That's sunlight glinting off a satellite, which can look like a bright orb that appears and fades. The FY2024 report describes a pilot's "white flashing lights" that lined up with a Starlink launch from Cape Canaveral about an hour earlier. If you've seen a string of lights moving in a line, read our Starlink satellite train explainer.
Birds are another big one. The FY2024 report says birds often show up on military video as an "amorphous blob or orb" because of compression and pixelation, and that "flickering" in the footage is usually flapping wings. That ties into why UAP photos are blurry.
Why doesn't "unexplained" mean alien?
Because most unexplained reports simply don't have enough information. AARO's active archive is, in its own words, for "cases lacking sufficient data to facilitate analysis." They can be reopened if new data turns up. In FY2024, 170 reports (22.4%) didn't even include enough detail to describe the object's shape.
The small group flagged for "further analysis" is the closest thing to a true mystery. The 2024 report says those cases have "reported anomalous characteristics and/or behaviors" that AARO is still working on with intelligence and science partners. Reported isn't the same as confirmed, and AARO hasn't announced that any of them is non-human.
Blue Book reached a similar place in 1969. Its closing conclusions, quoted on the National Archives page, say there was no evidence that "unidentified" sightings were "extraterrestrial vehicles" or technology beyond the science of the day. People who think that conclusion was wrong, or that something is being held back, point to witness testimony and the cases that stayed open. That's a claim about what we don't know, and it's worth keeping separate from what the files show. If you want to read the original case files yourself, our guide to declassified UFO documents lists where each collection lives.
Where do most UFO sightings happen?
In the official data, where the sensors are. Every official report since 2021 notes a "collection bias": reports cluster around military training ranges and restricted airspace because that's where trained crews and good sensors operate. The FY2024 report counted 100 reports from U.S. forces over the East Asian seas and 57 from the Middle East.
Civilian databases tell a different story, because they count where people live and report. The U.S. leads raw totals worldwide, as we explain in which countries report the most UAP.
What about NUFORC and other civilian databases?
The National UFO Reporting Center calls its databank "the largest independently collected set of UFO / UAP sighting reports available on the internet." NUFORC staff now grade reports in four tiers, from the most dramatic to ones they consider explainable. But the center also says it "makes no claims as to the validity of the information," and reports received before March 2023 haven't been graded yet.
That makes civilian databases useful for spotting trends and finding witnesses, not for answering how many sightings are explained. Their totals can't be added to the government's, and some events land in both.
Have there been any UFO sightings lately?
Yes. New reports keep coming in: AARO logged 319 in its latest reporting year, and civilian databases add more every week. For the latest cases and releases, see our weekly UAP news roundup and the Pentagon's own PURSUE releases, which we track in what's in the Pentagon's UFO files.
If you saw something, write it down while it's fresh and check a flight tracker and a satellite app first. Our guide to reporting a UAP sighting lists the channels, and what UAP look like covers the shapes people report most.
What's still unknown?
- What the "further analysis" cases are. AARO hasn't published a resolution for most of them.
- Whether the active archive will shrink. The share resolved went up as AARO added satellite modeling, but most archived cases may never get more data.
- How civilian and government counts overlap. Nobody has published a reconciled total.
- AARO's next annual report, covering June 2025 onward, hadn't been published as of November 10, 2026. The FY2025 report, posted July 20, 2026, is still the latest on AARO's reports page.

Questions people ask
How many UFO sightings are reported each year?
In the U.S. government's data, a few hundred a year. AARO received 757 reports in its FY2024 period and 319 in FY2025, which ended May 30, 2025. Its total holdings reached 1,870. Civilian databases such as NUFORC log their own reports separately.
Have there been any proven UFO sightings?
Not of anything non-human. Every case AARO has resolved turned out to be an ordinary object such as a balloon, bird, drone, aircraft or satellite. Its 2024 report says it has found no evidence of extraterrestrial beings, activity or technology. Some reports remain unexplained, mostly for lack of data.
What percentage of UFO sightings are explained?
About a third of each year's new reports in AARO's last two annual reports: roughly 39% in FY2024 and 36% in FY2025. About 60% went to an active archive for lack of data, and under 3% were flagged for further analysis. Project Blue Book left about 5.6% of 12,618 sightings unidentified.
What do most UFO sightings turn out to be?
Balloons, birds, drones, aircraft and satellites. AARO's FY2025 report resolved 238 cases as satellite flaring, sunlight glinting off satellites, and also explained one rocket launch and one jet pack.
Where are most UFO sightings in the US?
Official reports cluster near military training ranges and restricted airspace, because that's where trained crews and sensors are. The government calls this collection bias. Civilian databases instead track where people live and report, so their hotspots differ.
Has there been any UFO sightings lately?
Yes. Reports keep arriving at AARO and at civilian databases. AARO's FY2025 report, posted July 20, 2026, is the latest annual tally as of November 10, 2026. UAP Press tracks new cases and releases in its weekly UAP news roundup.
