Through 1917 three shepherd children near Fátima in Portugal described visits from a lady brighter than the sun, on the 13th of August, September and October, and the October visit was predicted in advance. On 13 October a crowd gathered in the rain to see it. Estimates in the tellings run from about 12,000 to more than 70,000. Many reported the sun as a brilliant spinning disc of shifting colour making low swooping passes over the crowd. One account describes a flattened spheroid that circled overhead and radiated enough heat to dry soaked clothes. A reporter named Alfredo Fandricas is said to have photographed a ball of light below the clouds.
What the record holds
The archive resolves seven claimants across two channels and four videos, and that figure needs a caveat: the claimant list mixes named individuals with crowd estimates, and the reporter may still surface under a second spelling. The identities are less clean than the count suggests. What the tellings agree on is the shape of the day: a predicted date, a very large crowd, and an aerial or solar display that thousands described. They also carry the day's most useful sceptical anchor. Greenwich Observatory recorded the sun in its normal position throughout, so whatever the crowd watched, the sun itself did not move. Sceptical readings have long pointed to mass expectation and the optical after-effects of staring at the sun through broken cloud; the record here neither tests nor settles them.
About the tier
The case grades L4 for one narrow and checkable reason. The CIA's declassified UFO collection contains a document referencing Fátima, and the system counts a government primary document naming a case as a corroborating record. That is what the badge reflects, a government file that mentions the event, and nothing more. It is not the United States government confirming a miracle. A journalism piece in the file is classed as reporting and carries no weight in the grade. Fátima remains what it was: a religious mass apparition of enormous cultural weight and contested cause. Tens of thousands of people gathered at a predicted moment and reported something in the sky, and the record of it has survived for over a century. Reports, not reality.
