ALSACAT:

As its name suggests, 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 Thann, on July 8, 1952:

Case number:

ALSACAT-1952-07-08-THANN-1

Summary:

The regional newspaper L'Alsace in its Colmar issue for July 10, 1952, reported that on Tuesday, July 8, 1952, in the evening, two female residents of Thann going through the Kléber street had seen very distinctly two vertical discs of bluish color come out of the clouds and move fast from west to east where they were lost from sight in the clouds.

The newspaper said that these saucers, "if there were saucers" were accompanied by a small trail of light, they seemed to fly quite low, and they were observed only for about twenty seconds.

The story was later falsely dated July 6, 1952 and cataloged as a UFO, without mention of the trail, by French ufologist Jacques Vallee.

Two "flying saucers in the sky of Thann

Tuesday evening, two female residents of Thann, going through the Kléber street saw very clearly coming out of clouds two vertical discs of bluish color, moving at a great speed from west to east to disappear back into the clouds. The saucers, if there were saucers, were accompanied by a small luminous trail. They seemed to fly quite low. The apparition lasted only twenty seconds.

[Ref. jv1:] JACQUES VALLEE:

Jacques Vallée indicates that on July 6 [sic], 1952, two bluish "discs" were seen in Thann in Alsace.

[Ref. ud1:] "UFODNA" WEBSITE:

6 July 1952 12:00

Thann, Alsace, France

Unidentified objects were sighted, but with appearance and behavior that most likely would have a conventional explanation. Two objects were observed in a town for a few seconds.

[Ref. cv2:] CHRISTIAN VALENTIN:

Former journalist Christian Valentin published in 2012 a very interesting book telling the story of UFO sightings, flying saucers sightings, in Alsace, from the beginning to 1980.

In this book, he reports that the newspaper L'Alsace published in their Colmar issue what followed on Thursday July 10, 1952:

Two "flying saucers in the sky of THANN

Tuesday evening (July 8, 1952), two female residents of Thann, going through the Kléber street saw very clearly coming out of clouds two vertical discs of bluish color, moving at a great speed from west to east to disappear back into the clouds. The saucers, if there were saucers, were accompanied by a small luminous trail. They seemed to fly quite low. The apparition lasted only twenty seconds.

Discussion:

It is quite tempting to think, with this mention of the trails, the brevity of the observation, and the total absence of anything that would that contradict it, that the two residents saw a double meteor.

Below, an aerial view of Thann with the position of the Kléber street.

Evaluation:

Possible meteor.
