Sicily, Italy — 11 May 1835
Astronomer’s sighting
Unknown luminous object reported by astronomer Cacciatore. It was observed on four consecutive days. “Cacciatore noted what he first believed was an eighth magnitude star on May 11, 1835; but, with his next observation, on May 14, 1835, its position had changed relative to another star, and he thought the object either a comet or planet beyond Uranus. Clouded skies prevented further observations until June 2, 1835; but, by then, the object had been lost.”
