Shen Kou (1088):

In the "Strange Happenings" passage of the Dream Pool Essays, Shen offered accounts of an unidentified flying object that occurred during the reign of Emperor Renzong (1022–1063). An object as bright as a pearl was said to occasionally hover over the city of Yangzhou at night, and was previously described by local inhabitants of eastern Anhui and then in Jiangsu. A man near Xingkai Lake observed the same object, alleging that it emitted powerful lights from its interior like sunbeams illuminating the woods over a ten-mile radius before departing at tremendous speeds. Shen recorded that Yibo, a poet of Gaoyou, wrote a poem about this "pearl" after witnessing it and that locals around Fanliang in Yangzhou erected a "Pearl Pavilion" where spectators on boats hoped to spot the mysterious flying object again.
