The phenomenon is actually caused by large-scale commercial fishing fleets. These vessels use high-intensity red LED light arrays to attract schools of Pacific saury, a type of fish that is naturally drawn to this specific light spectrum. When hundreds of boats gather, their collective illumination is bright enough to be seen from thousands of feet in the air. The original photos were taken by an anonymous pilot and first gained massive viral attention on Reddit in July 2022. While the text in your image mentions the Atlantic, most experts and flight logs from the period associated the sighting with the Pacific Ocean, where saury fishing is a major industrial activity.
