The Bonilla observation was an astronomical event in 1883 in which hundreds of unidentified flying objects were observed and photographed by Mexican astronomer José Bonilla.[1]
The photographs taken during the Bonilla observation are generally regarded as one of the first known examples of photographs of "unidentified flying objects".[2] Though the objects were assumed to be flocks of high-flying geese, astronomers have suggested more recently that Bonilla was observing a nearby comet breaking apart.[3][4]
