A recent example is the repeated appearance of a typical UFO phenomenology at Fatima,Portugal on six succesive months in 1917.
The October 13th phenomenon was the best reported and was witnessed by a crowd of about 70,000 persons,including a number of scientists,reporters,atheists and agnostics as well as faithfull catholics.
One of the scientifically curious was Dr A. Garrett of the University of Coimbra.
Rain which had been falling that day ceased and the crowd looked up to see the 'sun' now visible through the heavy clouds.
Professor Garrett wrote
"I turned towards this (sun) which was attracting all eyes and could see it was like a disc with a clear cut edge,with a vivd rim,luminous and shining but without hurting one.
The comparison I have heard at Fatima with a disc of dull silver does not seem to me exact.It was a clear,more vivid richer colour and with shifting tints like the lustre of pearl.
It was not at all like the moon on a clear transparent night for one saw and felt it like a living star.
Nor was it spherical like the moon,nor did it have the same quality of lighter and less light.
It looked like a burnished wheel cut out of mother of pearl.
Nor could it be confused with the sun seen through a fog...there was no fog.
This disc spun dizzly round.It was not the twinkiling of a star,it whirled round upon itslef with mad rapidity

A young woman was driving at 40-45 mph along Lake Cook Road, when her car suddenly lurched to the right for no reason that was apparent to her. There were no cars within sight on the road, and she had not seen any pedestrian or animal near the car. She stopped her car immediately, got out, and apparently was flabbergasted by the appearance of the left side of her automobile.

The investigating police officer could not provide an adequate explanation for the damage. He noted that there was no damaged paint, and no animal hair, feathers, or blood, evident on the damaged area of the car. NUFORC has passed the case along to Mr. Sam Maranto, Illinois State Director for the Mutual UFO Network (“MUFON”), for follow-up investigation.
