PM ang läget 20/8 beträffande rymdprojektiler

This memorandum, dated August 20, 1947, from the Swedish Defence Staff (Försvarsstaben), provides an update on the status of 'space projectiles' (rymdprojektiler). The document outlines the methodology used to process sighting reports, noting that due to the incompleteness of the data, certain assumptions were made to categorize observations, such as assigning missing altitude data to a 'greater than 2000m' column. The author discusses the ongoing effort to isolate potential meteor sightings from other phenomena by grouping specific time intervals. A meeting originally scheduled for the day of the report was postponed until the following day. The document highlights a failed attempt to determine the altitude of objects observed in Eskilstuna on August 11, as three separate calculations yielded vastly different results (1.2 km, 10.6 km, and 5.5 km), suggesting either significant errors in angular estimation or the observation of multiple distinct objects. The report also mentions that physical evidence, specifically metallic pieces identified as potentially metallic zinc, was sent to the FOA (Swedish Defence Research Agency) from the Lv 5 military unit. While the author notes there is no confirmed connection between these metallic pieces and the reported light phenomena, they acknowledge that no explanation could be found for how the pieces arrived at the site. Finally, the document lists three specific reports from August 17, 18, and 19, involving sightings of glowing blue-white spheres, sharp light objects, and reports of whining sounds without visual confirmation.
