Report from Norrtälje regarding the light phenomenon on Tuesday, July 9, 1946

This document is a report regarding a light phenomenon observed on July 9, 1946, near Norrtälje, Sweden. At approximately 12:30, an elongated object was seen flying in a southeasterly direction along a strongly curved path. The object was described as having an intensely glowing white-green tip and a blue-white-green tail measuring approximately 25 to 30 meters in length. The object appeared to impact a nearby field. Approximately 1.5 hours later, a reconnaissance of the field was conducted, and a physical object was recovered. The ground at the site showed no signs of scorching or impact craters. The object was initially intact but broke into pieces upon recovery, leading the observer to initially suspect it was ordinary slag. The observer, Oskar Lindh, subsequently had a chemist from the Norrtälje Foundry analyze the material. The analysis identified traces of diatomaceous earth, charcoal, and a minimal amount of metal, noting that the material's weight differed from typical generator or foundry slag. A subsequent laboratory examination at FOA,1 described the sample as two fist-sized, porous, gray pieces with a specific gravity of 2.4 to 2.5. Microscopic analysis revealed grass roots growing into the pores of the material, suggesting that the object had been lying at the recovery site for a significant period of time.
