Incident Report Compilation: Unidentified Aerial Phenomena Sightings in Sweden

This document is a tabular report detailing several incidents of unexplained water disturbances in Sweden during July 1947. The report covers four distinct locations: Kölnjärv, Rödupp (Kattisträsket), Kamlunge, and a site near Kalix. Witnesses reported phenomena such as water fountains, splashing, and sounds resembling motor hums or rushing water. In the case of Kölnjärv, a witness described an object approximately 1.5 to 2 meters in size with a gray-brown color and possible wings. At Kamlunge, multiple witnesses observed a powerful water column rising in the river. Military personnel from Ing 3 conducted investigations, including the use of divers, but were unable to determine the cause of the disturbances. One specific site near Kalix featured a crater in the riverbed, which investigators suggested might have been caused by a boat propeller, ultimately recommending no further action.
