Rapport ang ljusfenomen (Report regarding light phenomenon) — Linköping, August 12, 1946

This document is a formal military report issued by the Regimental Office of the Royal Life Grenadier Regiment (Kungl. Livgrenadjärregementet) in Linköping, dated August 12, 1946. The report details a sighting of an unidentified aerial phenomenon observed on August 10, 1946, at 20:47. The witness, Ensign Cars of the I 4 unit, observed the object from the Belvederens restaurant, located 1650 meters west of the Tannefors station. The object was described as a sharply shining, green-yellow sphere with a tail estimated to be 30 meters long. The phenomenon was first spotted over the SAAB airfield and traveled in a straight south-to-north direction at an estimated altitude of 300 meters. The witness noted that the front of the tail was bright yellow and compact, while the rear thinned out and appeared to shed glowing particles that fell toward the ground at a reduced speed. The object's speed was compared to that of a Vampire aircraft. The phenomenon was observed for approximately five seconds before it appeared to extinguish at the height of the southern shore of Lake Roxen. The report was signed by Acting Chief of Staff Dag Danielsson and addressed to the Air Defense Department of the Defense Staff.
