Iakttagelse betr rymdprojektil (Observation regarding space projectile)

This document is a formal report dated September 4, 1946, from the Kungl. Karlsborgs Luftvärnsregemente (Royal Karlsborg Anti-Aircraft Regiment) to the Swedish Defense Staff's Air Defense Department. It details an aerial observation made on the evening of September 1, 1946, at 22:38. The witness, an individual with a stated interest in astronomy and experience observing meteors, was walking near the fortress in Karlsborg with Captain Granlund and his wife when they observed a luminous sphere. The object moved at extreme speed from the northeast to the southwest, remaining visible for approximately one second. The witness described the object as having an intense, blinding white light, similar to magnesium, with a faint yellow tint. It appeared to 'flake off' while maintaining its size and left a luminous tail at least 40 degrees long. The witness noted that no sound was heard and that the object's path was perfectly horizontal, which he found highly unusual compared to his previous experiences with meteors. He concluded that if the object was a 'space projectile,' it must have been at a very high altitude. The weather conditions at the time were reported as very good and cloudless.
