Strange changes were reported to an isolated object in the eastern part of the moon’s Mare Serenitatis, known as Linne. Before October 1866, Linne was well-known as a dark object. On Dec. 14, 16, 25 and 27 of 1866, Linne was seen as a white spot. “But,” Fort writes, “there was something that had the seeming more of a design, or of a pattern, an elaboration upon the mere turning to white of something that had been black.” Sunlight seemed to have nothing to do with its changing appearance.
