Report on Light Phenomenon Sighting — Sundsvall, Sweden, July 9, 1946

This document is a formal report issued by Captain R. Westlin of the Royal Sundsvall Anti-Aircraft Corps (Kungl. Sundsvalls Luftvärnskår) to the Chief of the Defense Staff's Air Defense Department in Stockholm, dated July 16, 1946. The report provides details regarding a sighting of a light phenomenon that occurred on July 9, 1946, at 14:35. The witnesses, a watchmaker from Sundsvall and an ensign (fänrik) from the Swedish Air Force, were located at Bergafjärden, approximately 1.5 Swedish miles south-southeast of Sundsvall. They observed an object described as an intense 'drop' of light with a wide, tapering trail of light smoke. The witnesses reported that the object moved across the sky in a northeasterly direction, following a downward trajectory aligned with the sun's rays. Additionally, they noted glimmers of light appearing parallel to the smoke trail on both sides. The object reportedly ceased to be visible in the air, disappearing without any sudden flare or explosion. The report notes that while the ensign intended to report the sighting, the watchmaker had not filed a report. Captain Westlin concludes by noting that while the 'drop' shape is a detail reported by several other observers, the specific observation of glimmers of light on the sides of the smoke trail is unique to this account.
