A Black Triangle Reported over Aligarh, Uttar Pradesh
The witness reached for his camera, found it in selfie mode, and by the time he turned it round the object had gone. That sentence is the whole evidentiary problem.
What did witnesses see at Gopal Puri?
A man on his terrace in Aligarh, Uttar Pradesh reported a silent black triangle crossing the sky on 18 October 2026. He was alone, the object carried four dim lights, and he has no photograph of it.
The structured filing puts the sighting at 9:06 PM IST on 18 October 2026, from an address in Gopal Puri near Gyatri Mandir in Aligarh. One object is reported, triangular, at a distance he gives as a few miles and an apparent size of a quarter held at arm's length. The duration is two seconds. There is one witness. His description is that the object was black and triangular, made no sound, moved in a straight line at constant speed with no hovering and no sudden turns, carried four dim lights, appeared medium in size, and faded after two or three seconds under what he calls a clear sky.
He is explicit that this was not his first. He describes an earlier sighting about six or seven months previously, also a black triangular object flying over silently and visible for only two or three seconds, with no time to get a phone out. For the October event he says he checked a flight tracking application and found no flights in that direction, and he compares what he saw to the TR-3B, the triangular craft of long standing internet rumour.
In the comments he adds a third claim. He says he saw four more of the objects on 19 October, the day after, that he took a picture but his camera is poor, and that in his observation they appear between 8 PM and 9 PM daily. No image from that night has been posted.
What is the official explanation?
No Indian agency has commented, no outlet has covered it, and there is no official narrative of any kind to weigh. The report exists only as a structured filing relayed to Reddit.
The automated sky context block attached to the filing reports that no bright satellites were visible overhead, computed from a 2026-10-18 catalogue. Taken at face value it removes the commonest night light candidate, and in this instance its stated time matches the reported time, so it does not suffer the misalignment that has invalidated the same block on other cases in this archive. It is still a lead and not a verdict.
The ephemeris was run independently for the site. At 15:36 UTC on 18 October, which is 9:06 PM IST, Saturn stood at azimuth 126.0 and altitude 50.2 and the Moon at azimuth 222.0 and altitude 23.6. Everything else was down: the Sun 44.7 degrees below the horizon, Venus 43.9 below, Jupiter 45.3 below, Mars 37.7 below and Mercury 29.6 below. Two bright natural objects were up, neither of which is a dark triangle carrying four lights, and the witness reports no bearing so neither can be tested against his line of sight.
The sky itself is the part of the record that matters most, and the witness's description of it is wrong. Aligarh has no reporting station. The nearest with a public archive is Indira Gandhi International at Delhi, about 130 kilometres north west, and it logged haze through the whole of 18 October: visibility fell to 1.2 kilometres before dawn, recovered to 4.0 kilometres by mid morning and sat at 4.0 kilometres through the evening, reading 4.0 kilometres at 15:30 and 16:00 UTC, which brackets the sighting. Cloud was reported as nil significant. Agra, closer to Aligarh, holds a thinner record for the same day. The witness called the sky conditions clear. The nearest instrument available calls it four kilometres of haze with no cloud, which is a sky that looks clear overhead and swallows anything at a distance.
What did the witnesses think it was?
The thread was friendly and added nothing evidentiary. One commenter praised the documentation and remarked that sightings do happen in India but the attention stays on the United States. The witness replied with the claim about four more objects on 19 October and the daily eight to nine in the evening pattern. The same commenter asked to see whatever he catches. No corroborating witness, photograph or video has appeared.
The reason there is no image is recorded in the filing in the witness's own words, and it is worth quoting because it is so ordinary: he opened the camera application, it opened in selfie mode, and by the time he switched to the rear camera the object had gone. Anyone who has tried to photograph something unexpected in the sky recognises that sentence. It is also the reason this case will probably never be more than it is now.
Is the A Black Triangle Reported over Aligarh, Uttar Pradesh real? The two-pass assessment
Pass one, how could this be mundane. A dark shape carrying four dim lights, travelling in a straight line at constant speed, silent, and gone in two to three seconds is the description of an aircraft. The two details the witness offers as strange both point the other way.
The first is the fading. He says the object faded after two or three seconds rather than passing out of sight behind something or departing at speed. Fading is what haze does. The nearest instrument puts four kilometres of visibility over the region that evening, and at that visibility an object at the few miles he estimates is right at the edge of the extinction limit, so it would emerge from the murk, cross a patch of sky, and dissolve back into it. His own stated distance and the measured visibility agree with each other and they agree with the behaviour he reports.
The second is the silence. An aircraft at a few miles slant range, in a city, under a hazy evening sky, is frequently inaudible from a terrace, and silence at that distance carries very little weight.
His flight tracking check is the strongest thing in his favour and it is also the weakest kind of evidence to rely on. Consumer tracking applications show aircraft that broadcast ADS-B and are within range of a nearby receiver, with coverage over inland northern India that is patchy and with military traffic frequently absent entirely. A negative result from such an application is not a demonstration that the sky was empty. Aligarh sits roughly 130 kilometres south east of Delhi, under one of the busiest airspace regions in Asia, and that is the context in which a four lighted shape passing in a straight line has to be weighed.
The comment claim deserves its own line, because it is the most testable statement in the file and it cuts in the prosaic direction. The witness says these things appear between 8 PM and 9 PM daily and that he saw four more the following evening. A nightly recurrence in a fixed time window over a fixed location is the signature of a scheduled traffic pattern, not of an anomaly. If it is genuinely nightly then it is also the easiest thing in this archive to photograph, and the witness has already said he has a camera and has tried.
Pass two, if it is real. The honest statement of the pro case is thin and should be stated as thin. One witness, alone, with no instrument, reporting a two second event under a four kilometre haze, who has nothing to show for it and who compares what he saw to a craft he already knew about from the internet before he saw it. None of that makes him wrong. It does mean there is nothing here that can be tested, and the archive is recording a report rather than analysing an event.
Tiered Unknown, which is what this archive calls a case with no official narrative and no demonstrated explanation. The aircraft reading is a candidate with the haze, the distance, the straight constant track and the nightly recurrence behind it, and it is not a result, because no flight has been identified. The case is published because it is real, recent, located and honestly filed, and it is published short because that is all there is. It will be revisited if the witness posts an image, and his own account says he is trying.
