Prov nr 1 (Sample No. 1) - Njurunda, 1946

This document is a laboratory report from the Swedish National Defence Research Institute (FOA) regarding a physical sample (Sample No. 1) recovered in Njurunda on July 9, 1946. The sample was received by FOA on July 12, 1946. It was accompanied by a report from the newspaper Sundsvalls Tidning, which stated that the sample was discovered by an editorial secretary named Granberg. According to the report, the impact site in the sand was approximately one meter wide and a few decimeters deep. The sample itself was found ten meters from the impact pit, in the direction of travel. Local residents had reportedly collected additional scrap material of a similar quantity to the box containing the sample. The FOA analysis describes the sample as weighing approximately 20 grams and having a rust-brown color with light yellow inclusions. The object features concave cylindrical surfaces, which the analysts suggest indicate contact with a tubular body. These specific surfaces are darker, glassy, and non-porous, with this characteristic extending one millimeter into the mass. The rest of the material contains larger and smaller bubbles, with the larger ones lined with glassy material. The sample is porous and absorbs water quickly, yet it is difficult to dry out. The material is soft enough to be worked with a knife, although the cylindrical surfaces are significantly harder. Under a magnifying glass, the material appears to have been in a molten or sintered state. Microscopic examination reveals lighter parts embedded in a harder, amber-like structure, with sand grains found in the cavities.
