Sighting Report — Vanadisplan, Stockholm, August 11, 1946

On August 11, 1946, at approximately 20:47 to 20:48, two individuals, Gunnar Fredrikson and Bengt Wallberg, observed a luminous object from Vanadisplan in Stockholm. The witnesses reported that the object was traveling in a north-westerly direction, having originated from the south. The object was described as emitting a bright white light, comparable to magnesium light, and possessed a tail that faded as the object moved. The witnesses noted that the object's light intensity decreased gradually during the observation. The flight path was described as horizontal or slightly upward, and the object eventually disappeared at an elevation angle of approximately 45 to 50 degrees. The witnesses remarked that the object bore a resemblance to some form of firework, though its trajectory did not conform to such an explanation. They further stated that it was impossible to judge the object's altitude above the ground. No sound was reported in connection with the sighting. The report was submitted to the Air Defense Department of the Defense Staff in Stockholm.
