A historical UFO event from 11/17/1892 near Nanjing City, China
On the evening of November 17, 1892, an egg-shaped red fireball was observed moving much slower than a typical natural fireball from west to east, south of Jinling / Nanjing City, China. The hundreds of observers were obviously very familiar with the appearance of sky lanterns, and this appeared to not travel with the wind. Acting like an early field investigator, the artist Wu Youru ( 吴友如 ) interviewed many witnesses and documented the sighting in a painting, "Soaring Scarlet Flame in the Sky" ( 赤焰騰空 ), complete with notes on why it was not a natural fireball or sky lantern: https://zh.wikipedia.org/zh-cn/%E8%B5%A4%E7%84%B0%E9%A8%B0%E7%A9%BA%E4%BA%8B%E4%BB%B6
"On September 28th, at eight o'clock in the evening, south of Jinling city, a fireball suddenly appeared, moving from west to east, shaped like a giant egg, red in color and without luster, drifting in midair, moving very slowly. At that time, floating clouds covered the sky, and the sky grew dark. Looking up, it was very clear: standing atop the Vermilion Bird Bridge, there were no fewer than several hundred people craned their heads and tiptoed on tiptoe. After about the time it takes to cook a meal, gradually fading away, the distance gradually diminishes. Some say that a shooting star passes through the realm, but when the star travels swiftly, it vanishes in an instant. This sphere moves from near to far, exists on its own yet is absent, and is quite damp and stagnant, so it cannot be known by the speed of a star. Some say that when children release sky lanterns, that night a storm blew northward, causing the ball to turn eastward, so it is clear it is not a sky lantern. Voices of the crowd were at a loss, exhausted in speculation. An old man said, when this creature first arose, he faintly sensed a sound, but it was not something one could hear quietly; it was connected to the Yue River outside the South Gate. Ah, how strange!" Wu Youru, "The Record of the Red Flame Soaring into the Sky"
