Incident Reports: Light Phenomena, August 11, 1946

This document, identified as Fobef 53-54, records two separate reports of light phenomena observed on August 11, 1946, at 20:50. The first report was provided by an engineer named John G. Carlsson from ASEA in Ludvika. He described a spherical, brightly shining object observed at Norsbro (map sheet 90) moving from the southeast toward the northwest. A second observation, also at 20:50, was reported from Persbo, 5.7 km north of Norsbro, where a witness observed a shining object at low altitude that appeared to strike down into a field between the railway and the road. The second report came from an accountant named Herou in Falun. He observed the phenomenon near a road junction between a viaduct and the railway in the area of Karlsvik, 3.2 km west of Hinsnoret station (map sheet 97 Falun). Herou described the object as a fireball at an altitude of 40 meters, noting that it made no sound and followed an arched trajectory, appearing like a large rocket with sparks trailing behind it.
