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 Mulhouse, on July 10, 2003:

Case number:



"Olivier", from Mulhouse, had reported on February 3, 2005, by email to the Swiss ufology group GREPI, that the day before, he had accidentally photographed a UFO in the shape of a black disk in the sky.

On this occasion he also reported this earlier visual observation:

On July 10, 2003, at exactly 1 p.m., he was eating on their terrace with his mate, when they saw "a white sphere surrounded by a halo in the sky, emerging clearly in the blue sky of that beautiful sunny day."

"This sphere has described a curve up (like a smile, but vertical) and disappear relatively quickly in the sky."

He stated that "the phenomenon lasted about 1 minute."

He commented that he had long dreamed "to observe such a phenomenon," that it made him happy, and he added:

"I am among those who think that we probably have brothers somewhere in the universe waiting to meet us in peace."

Yesterday afternoon (Monday, February 2, 2004 at 01:25 p.m.) we photographed our little girl, just like many parents do (with a digital camera, Santa's gift) and when we looked at the pictures on our computer, we observed on one of them a small black disc on the horizon just above the head of our little girl.

We then looked more closely at this photo with the Photoshop software, we expanded the area where the disc is located and noticed that there was symmetry in the shape and colors of the disc.

To be sure about it, I photographed a few minutes later in the same place, birds and planes passing through there, to compare and enlarge objects on the shots with the one we had of the disc.

I could not see no similarity with it. I think we have once again and certainly observed a UFO on a random photo.

I say again, because this summer 2003, July 10 at 13h exactly was had seen saw a white sphere surrounded by a halo in the sky, emerge clearly in the blue sky of this beautiful sunny day. This sphere had followed a curve up (like a smile, but vertical) and disappeared relatively quickly in the sky.

The phenomenon lasted about 1 minute.

We were, my mate and, I eating on our terrace.

I have been dreaming for a long time to observe such a phenomenon, and I'm most happy I did. I wish all those who wish to observe at least once in their life a UFO, the feeling is the biggest and one does immediately realize that this is unusual and spectacular. I am among those who think that we probably have brothers somewhere in the universe waiting to meet us in peace.

Now, do you know a person or persons able to study the photo and give their professional opinion? If this is the case, contact me. We live near Mulhouse in Alsace.

Best regards.

Olivier (Alsace - France)


Note: the image sent is a different issue, and it is dealt with in its own file here.

As for this visual observation, the information is unfortunately too meager to make any decision: the exact location is unknown, there is no angular size, no angular displacement, no heading, no elevation etc.

Of course it could have been an alien spacecraft. I cannot prove otherwise. However, its seems to me it could have been a balloon, toy balloon or weather balloon, or some plane or something else.


Possible balloon or plane.
