15 September 1952, Mora, Sweden
"The two pictures taken by Nils Frost in Mora on 15 September 1952 are still unexplained and the motifs are classified as genuine UFOs.
One of the pictures shows two objects against the dark night sky somewhat above the tree tops. One object seems closer to the photographer than the other. A laboratory analysis has shown that a perfectly round object like a miniature sun is hidden at the centre of the bright light."
