Le 1er février 2025 à 20h28, le témoin stationné sur une petite route de campagne à proximité du village d'AVESNES-LES-AUBERT (59), procède à une série de prises de vue en mode time-lapse à l'aide de son smartphone, dans le but de photographier la Lune et la planète Vénus. La séquence dure environ quatre minutes. Une image extraite du time-lapse, ainsi que le fichier complet, sont transmis au GEIPAN le 11 février 2025 via un lien de téléchargement, accompagnés d'un Questionnaire Technique (QT) dûment complété. Le témoin n'observe pas de visu le PAN, mais uniquement a posteriori, en visionnant le résultat de ses prises de vue. Dans un premier temps, il envisage la possibilité d'un artefact lié à la prise de vue numérique, avant de noter que le déplacement de l'objet évoque, selon ses termes, « le mouvement d'un satellite ». Une analyse astronomique depuis Lille avec l'outil Stellarium (logiciel libre d'affichage du ciel de manière photo-réaliste en temps réel) confirme la présence de la Lune et de Vénus, visibles dans le ciel à l'heure de l'observation (Annexe 1). De bonne consistance*, bien qu'il n'y ait qu'un seul témoignage, l'analyse de la courte vidéo et de la photographie fournies permet de conclure que l'observation correspond probablement à un reflet parasite de la Lune dans l'objectif du smartphone utilisé par le témoin.. Cette hypothèse s'appuie sur les éléments suivants : - Le logiciel d'analyse photo du GEIPAN, IPACO*, intègre un outil spécifique à la détection de tels reflets. Cet outil a été utilisé dans le cadre de cette analyse et permet de démontrer sans ambiguïté, qu'il s'agit d'un reflet causé par la présence de la pleine Lune dans le champ de vision de la vidéo et de la photographie. Ce reflet se positionne systématiquement à l'opposé d'une source lumineuse intense, suivant un axe de symétrie centrale passant par le centre optique de l'objectif de l'appareil.. La méthodologie inhérente à l'analyse de cet artefact peut être consultée sur la page reflets optiques du site IPACO. - Un écart a été observé entre le centre géométrique de l'image et le centre optique de l'objectif. Cet écart peut être attribué à un léger décalage entre le centre du capteur d'image et le centre du système optique du smartphone. Cette différence a été clairement identifiée et mesurée à l'aide de l'outil dédié du logiciel IPACO (voir Annexes 2 et 3). - L'examen de la vidéo permet de constater le déplacement simultané, toujours selon un axe de symétrie centrale, de la Lune et de son reflet (le PAN noté par le témoin), mais également de Vénus qui produit également son propre reflet, quoi que moins visible que celui de la Lune. Deux mesures locales (en pixels) effectuées entre d'une part la Lune et Vénus et d'autre part leurs reflets respectifs montre que l'écartement est exactement le même (436 pixels). (Annexe 4). - Forme de croissant, comme celle de la Lune au moment des prises de vue (elle était illuminée à 13,2%). La forme du reflet est inversée, conformément à l'application de la symétrie centrale selon l'axe optique. - Couleur qui peut être bleue, verte ou rouge, typique de celle de la couche protectrice extérieure de la lentille externe de l'objectif. Nous ne savons toutefois pas si, pour le modèle particulier utilisé par le témoin, cette couleur est bien verte. Le témoin n'a pas été en mesure d'observer le phénomène à l'œil nu, celui-ci n'étant visible que sur l'écran de l'appareil au moment de la prise de vue, ou a posteriori, lors de l'examen des images sur un ordinateur. Le témoin confirme d'ailleurs avoir constaté la présence du phénomène uniquement après avoir visionné les photographies. Le GEIPAN classe cette observation en A : artefact parasite de reflet d'objectif de l'appareil de prise de vues. *selon les critères du GEIPAN, la consistance est la quantité d'informations considérées comme fiables et objectivées, recueillies pour un témoignage. *IPACO : Logiciel d'analyse et de traitement d'images du GEIPAN (IPACO.fr).

The object in the sky moved laterally, with no exhaust, and was smaller than an airplane. It was maybe one to two miles away from us. As we observed it in the sky it turned at an angle and seemed to reflect the Setting Sun and there was a flash of light on the side of the object. Immediately after that flash of light the object disappeared. There were no clouds that it would have disappeared behind, nor any other objects. It was a clear sky and we had a clear view of the object.

Tonight, on Dec. 8th, 2023, I saw a large air craft in the sky unlike any I have seen before. I saw it clearly. It was a chevron shaped craft, with a straight row of lights in the back. The lights were a greenish blue. The craft looked like dark gray metal. It was flying on a diagonal in the sky through my neighborhood. I called to my husband to run out and he took a video with his phone. By the time he came out, it was farther away. When I watched the video, the lights were behaving differently on the video than I saw with my naked eyes. This has now confused me a bit because now I can't remember how exactly the lights were behaving, but I noticed it was definitely different on the video than what I had seen. He said maybe it's a helicopter or a drone, but I disagreed and said it was shaped like a bat, and very huge, and I had watched it when it was closer and not so far away when he saw it in the cloudy sky. I drew a quick hand sketch of it when I came inside, and sent it to my friend. She found this sight and sent me back similar images. On this sight, I see the chevron as an option and that's the shape! I posted this on my facebook. Everyone is shocked! [NUFORC annotation: Balloon - Possible]

Austin, TX
Standing outside of my 12th-floor patio in my apartment building, I witnessed something approaching from North Austin with no visible lights (it was past midnight). Knowing this did not match commercial flight routes I had seen previously, I watched it fly almost directly overhead me in a south or nearly southeast direction. The first thing that came to mind was a stealth bomber like the B2, but I wouldn't understand why it was flying so low with no lights. I could clearly see the Chevron shape in a light grey tone, but couldn't discern whether it had a full triangle that was black or a darker color. I watched it fly above me for about 30 seconds, where once it got above I removed my headphones and heard no audible noise. At one point, I almost believed the front of the object changed shape from being a straight-angled Chevron, but I couldn't say this for certainty.

Object was spotted too far south to be UAL1871 or VAL804 and too north to be DHK379 Appeared to ascend to the south of Ferris wheel at nearby amusement park. Vertical ascent and lights made me consider a drone at first, as it was almost disk shaped, but as it moved across the sky I observed it make a number of unnatural course corrections. Lights pulsated around it left to right, red and white lights. Speed varied and seemed to slow down as I called up to it.

Another party and I were outside discussing the stars. We simultaneously noticed the craft above. The craft made no noise and was traveling at a low speed in the sky. It was almost the color of the the night sky, although a few shades lighter. Said craft then traveled southwest towards downtown and blended in with the lighter pitch of the city lights. The event was approximately 45 seconds in duration at approximately 2132 hours.

On Sunday November 5th of 2023 at 2:45pm at 86th and Zionsville Rd in Indianapolis, I was looking up into the sky when I observed a circular whirlwind and about 40 or more unidentified chevron winged aircraft in the sky. The aircraft was very high up and was visible for about 5 minutes. I only caught 52 seconds of it in video and I took 1 snapshot picture. Most of the aircraft had disappeared or fallen out of my view by the time I made the video and took a photo.

While sitting in my hot tub I was looking in a Southward direction waiting for the SpaceX rocket launch, when I saw what I thought was a shooting star, but then I realized there were more lights around what I thought was the star. The lights were in a chevron shape and were very dim. The object with the lights moved across the sky very quickly. It was out of my view within 3 or 4 seconds. The object appeared to be flat and made no sound as it moved across the sky. My boyfriend also saw it as he was in the hot tub with me.

At 1025 pm I pulled into the Walmart parking lot on Louis Ave Sioux Falls, A large chevron shaped craft was moving at a very low altitude (100ft to 150ft) approximately 300ft in front of me. The craft was flying slow probably about 30 mph just clearing the top of Walmart, the craft was about the size of a couple city buses and moved with zero noise, the skin of the craft seamed to be coated in a light absorbing material and appeared as a black chevron moving against the back lit sky with a sort of shimmer around the edges, the craft itself had no visible light what so ever it seamed to absorb light, if it were not for the city lit sky you would never see or hear it, because of the city lights it appeared as a chevron shaped hole in space. As it crossed the store heading north it banked east presumably to avoid a air plane that just took off from the air port on the north side of the city, by time I parked my car to get a better look it had moved into a darker part of the sky and was no longer visible against the back drop of the night sky.

It was very large, much larger than commercial planes flying overhead. It came from the north and was flying south east. It was a chevron shape, almost translucent in that it matched the night sky. There were “lights” that looked almost like small luminescent reflectors than actual lights, about 20-30 that were in the shape of the craft. It had a haze around it that helped make out the shape. It was flying quicker than the commercial craft. Absolutely silent. Flew straight and then in a weird sideways pattern before continuing on its original path. It did not appear to be any sort of plane or small military craft that is publicly known. It returned about 15 min later, following the same path. Without the haze and glowing quality (they almost looked like the appearance of distant stars except they were all moving together in formation) we would have not seen the object.

I was observing the night sky for only a few moments, when I noticed motion in my peripheral, to the north and about 80 degrees up from my location in my back yard. It was 12 or more very faint points of light forming a perfect chevron or boomerang. I watched the shape move in a linear constant speed from East to West with no sound. At first I thought it could be birds migrating, given its apparent size and silence from my perspective. But its shape was perfect and its path was perfectly straight. I could detect a shape that was greater than just the points of light as it passed over the stars, again like that of a boomerang or plane wings with no fuselage. From my perspective, if the form were a known aircraft, it would be most similar to a B2 Bomber. However, if it were a conventional aircraft, it would have been no more than 1000 ft above the ground. Which would have produced immense sound. Lastly, the appearance of the shape was mildly streaking or fluid in its motion. Almost like it was passing just below the surface of water. I observed it for 10-15 seconds, starting at approximately due north of my location, until I lost sight of it over the West horizon.

My girlfriend and I were on an evening walk up boucherie mountain in west Kelowna, Canada. Approximately halfway up there is a lookout spot which gave a great vantage point to the clear night sky. After admiring the stars for 10 or so minutes my girlfriend startled me by abruptly shouting out “what is that!?” And pointing into the night sky. After a brief moment my eyes came across what I can best describe as a bending of light, holding its form moving slowly across the sky at lower altitude. My uneducated guess would be maybe 10,000 ft in altitude, significantly lower than a civilian aircraft. We could not make out any details of any alien/military craft. Light appeared to be bending around an unseen object shaped almost as a chevron, but with a straight edged horizontal nose. The light bent/refracted around it was almost identical in hue to the particularly colourful deep tangerine moon. My girlfriend described the effect as looking like a “forcefield.” The craft/object moved in linear direction and speed, slowly moving across the night sky until travelling too far away to be seen. It did not leave behind any contrail. The size of said anomaly was maybe twice larger than the size of the Little Dipper, also present in the night sky. The lighting bent around it perfectly held its form, traversing a massive portion of the sky until travelling out of view.
