Inquiry regarding aerial phenomenon sighting in Guldsmedshyttan

This document is a formal inquiry dated August 5, 1946, from the Air Defense Department of the Swedish Defense Staff (Försvarsstaben) to the firing range manager at AB Bofors. The correspondence concerns a photograph of an aerial light phenomenon observed in Guldsmedshyttan on July 9, 1946, at approximately 14:30. The Air Defense Department notes that the phenomenon might be related to rocket testing at the Bofors range and requests an expert opinion on whether such tests were occurring at the time of the sighting. The document includes a report from an observer who described seeing a sharp, green-white, neon-like streak of light in a north-westerly direction. The observer reported that the object appeared suddenly, moved rapidly downwards for a distance estimated at five moon diameters, and then disappeared with an explosion-like flare accompanied by a hissing sound. The observer initially suspected it was a meteorite, though they noted they had never seen one during the day. The entire event was described as lasting only a blink of an eye. The document concludes with a directive that no information regarding this investigation should be shared with outside parties.
