angående rymdprojektiler (Regarding Space Projectiles)

This memorandum, dated October 28, 1946, and classified as 'HEMLIG' (Secret), was issued by the Swedish Defense Staff (Fst/FL) to the Chief of the Internal Department. The document addresses reports from observers regarding changes and interventions by Russian authorities concerning shipping in the Baltic Sea, as well as sightings of 'space projectiles' (rymdprojektiler) west of the island of Ösel. To assist in their investigations into these projectiles over Sweden, the Defense Staff requests continuous intelligence from the Internal Department. Specifically, the Defense Staff seeks information regarding two main areas: first, the timing of shipping restrictions, including which waters are avoided and which are permitted; and second, detailed observations of the projectiles, including time, course, altitude, speed, appearance, sound and light phenomena, radio interference, and the presence of any aircraft or ships. The document concludes by requesting that these observations be confirmed with photographs whenever possible.
