ALSACAT is my comprehensive catalog of UFO sighting reports in Alsace, the region is the North-East of France, whether they are "explained" or "unexplained".

The ALSACAT catalog is made of case files with a case number, summary, quantitative information (date, location, number of witnesses...), classifications, all sources mentioning the case with their references, a discussion of the case in order to evaluate its causes, and a history of the changes made to the file. A general index and thematic sub-catalogs give access to these Alsatian case files.

Case of Vosges, on September 27, 2013:

Case number:



On September 27, 2013, a teenager was at a geology field trip on a ridge path in the Vosges, and was taking landscape photography with his high definition mobile phone camera.

On the bus home, he noticed on one of his photos a "very strange thing." He talked about it the next day on the "" web forum, very popular among teenagers, publishing his two photos. There, some teens screamed at the "fake", while some other suggested the correct explanation.

The "strange thing" is simply a bird in flight, and then another or the same one on the second picture. Birds are often to blurred to be recognized as such at first glance on pictures, because of their movement during the exposure time. That is what ufologists - at least those who do not get excited about nothing - call "BLURFO", for "blurry UFO" or "surprise picture", these photographs where something that was not seen with the naked eye even when there was many potential witnesses, and puzzle people only later once they look at the picture on a screen.

Subject: 'I took a photograph of a UFO'

Posted September 28, 2013 at 02:59:50 p.m.

It was yesterday, we wer at a geology field trip, and about 2 p.m., I took a picture when I was walking down a mountain, and once in the bus I saw that very strange thing...:

At the top on the left, above the mountain

:d) This is not a faked picture, I don not know how to make them, and if you are a computer artist or something like that you can check that it is genuine :g)

But the strangest, this other picture I took about 4 sec earlier... Let me explain, I was walking down, so I was moving, and I took a picture. But I told to myself that as I was moving, the picture would be blurry, so I stopped and took another picture (the one above) without moving too much... And on that picture, it is also there...

Again on the top at the left between the 2 clouds (dust your screen, you will see it) by zooming, you see that it is 2 grey/black pixels, I think it is also the ufo... No plane can travel that fast in 4 seconds...

I thought of a fly or something like that but I really do have the impression that the "ufo" is above the mountain, and it is not some shit on the lens either, otherwise the spec would be the same on the 2 pictures... Yet I did not really believe in ufo before seeing this...

And I also specify that I did not see it, I just took the 2 photos and went on walking

Any ideas?

PS : I have a galaxy s4, this is why the picture has sich a high resolution (13 mpx)

The photographer says further on that "it was in Alsace" near Fellering. At the suggestion of a member, he said he sent his pictures to the official UFO investigation service GEIPAN.

The forum is not a ufology forum. It has 5 web pages of "comments" including rare suggestions that "it is just a bird," and a lot of "it's a fake."


EXIF metadata, which are in the files and show that the person published a real camera image - unless he had some expertise about EXIF metadata - indicates that the shooting of the first image is on 09/27/2013 at 01:23 p.m., the software is the smartphone software, I9505XXUMBGA, the resolution is 72 dpi, 4128*2322 pixels, the camera is a Samsung GT-I9505 (this is the camera of the mobile phone, focal is F/2.2, focal length is 4 mm, the maximum opening is 2.28, the exposure time is 1/1536 seconds, ISO speed is ISO-50, the flash was not used, the brightness is 8824, the color depth is 24, the software used normal exposure, the white balance was set automatically.

For the second image data is the same as the first, except the exposure of 1/2332 seconds, a little longer.

The photograph was taken on a footpath overlooking the famous "Route des Crêtes" (ridge road), where I have been hiking countless times since childhood.
