The José Bonilla UFO Observation

On August 12, 1883, astronomer José A. Y. Bonilla observed and photographed approximately 450 objects crossing in front of the Sun at the Zacatecas Observatory in Mexico. His photographs may represent the first photographic evidence of unidentified flying objects, though alternative explanations exist.

The Observer

José Bonilla was the Director of Zacatecas Observatory, a respected astronomer conducting solar observations using a telescope with camera to make scientific records.

The Observation

Over two days from August 12-13, 1883, a total of 447 objects were counted crossing the solar disc, moving in various formations, with some appearing to be surrounded by mist.

The Objects

Bonilla described dark, irregular shapes—some round, some elongated—moving across the sun, surrounded by glowing mist, and not matching any known phenomena.

The Photographs

Bonilla captured multiple images on wet plates showing objects clearly visible against the bright sun, potentially the first UFO photographs, which were published in a scientific journal.

Publication

The report appeared in L’Astronomie journal (1886) where the editor added a skeptical note suggesting birds or insects, which Bonilla disputed, sparking debate.

Modern Analysis

Recent studies suggest these were possibly comet fragments breaking up near Earth which would explain their appearance, though distance estimates vary and the interpretation is still debated.

Alternative Explanations

Proposed theories include migrating birds, insects near the telescope, atmospheric phenomena, comet debris, and genuine UFOs.

Arguments Against Mundane

Bonilla noted that the objects were very distant, their speed was inconsistent with birds, the duration of the sighting was extended, this was a professional observation, and there is clear photographic evidence.

Significance

The Bonilla observation is significant for potentially being the first photographed UFOs, having a professional astronomer as witness, providing scientific documentation, being published in a peer-reviewed journal, and remaining an ongoing mystery.

Legacy

José Bonilla’s 1883 observations represent a fascinating early example of UFO documentation. Whether comet fragments, birds, or something else, his photographs remain some of the earliest anomalous aerial imagery ever recorded.
