The José Bonilla Observatory Observation

Record summary

Astronomer José Bonilla reportedly observed and photographed numerous dark objects crossing the solar disk from the Zacatecas Observatory in 1883, publishing an account in the French journal L’Astronomie. The episode is relevant to UAP research because later writers interpreted the objects as a fleet, whereas astronomical and historical discussions have proposed birds, insects, debris, or other conventional explanations. The original article, surviving photographic material, observatory conditions, and later translations should be examined before drawing conclusions about distance, size, or nature.
