๐๏ธ March 1, 2025 โ Original German report uploaded to Zenodo. Previously published in JUFOF, issue 1/2025, No. 277; exact original publication date unspecified.
๐ On September 20, 2024, at 05:34 AM CEST, a Federal Police employee returning home from a night shift reported an unusual sighting in FriesenheimโOberweier, Germany. After stepping out of her car, she heard a loud noise resembling a metal chain being dragged across asphalt. Looking toward the southern sky, she observed a bright white, wave-shaped formation with two vertically aligned points of light in front of it. She estimated that the sighting lasted no more than five seconds, with the light and noise disappearing simultaneously.
Her husband, who was preparing breakfast indoors, also heard an unusual sound through the open balcony door. He described it as small beads falling onto a tiled floor, but did not see the luminous phenomenon. The witness checked the time on her Apple Watch and subsequently informed Josef Garcia, a GEP investigator living approximately one kilometre away.
Garcia reviewed recordings from his continuously operating passive radar station and identified a signal at the corresponding time. According to the article, its appearance closely resembled the witnessโs sketch. The author interprets this as independent confirmation of the sighting and argues that the recording indicates a stationary phenomenon lasting just over two seconds.
The investigation reportedly found no conventional aircraft in the area at the time, while weather information indicated clear skies. The article highlights the unusual visual appearance, brief duration and accompanying noise as the main features of the case.
Author Hans-Werner Peiniger describes the incident as, to his knowledge, the first visual UFO/UAP sighting confirmed by passive radar. GEP classified it as a โGOOD UFOโ case. The phenomenon remains unidentified, and the investigation is listed as on hold. Radar images, technical configuration details and the original case report were subsequently made available through Zenodo.

We investigate #passiveRadar imaging of aircraft using reflected TV signals. Such passive multistatic ``#radar'' was developed to detect & track aircraft with good accuracy. The capability of #imaging would help to identify stealth targets. #DSP #SAR https://t.co/OB9Vd4yP04

@Question2781 @TheProjectUnity Peter Davenport from @NUFORC would be great. Has been documenting / compiling all the US sightings since the 80's
- no idea why people don't talk to him. Also ask him about his #PassiveRadar paper.
