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 Ittenheim, on August 15, 1968:

Case number:



It seems that according to the Sélestat issue of Les Dernières Nouvelles d'Alsace for Tuesday, August 20, 1968, there was a sighting on August 15, 1968, at 9 p.m. in Ittenheim in the Bas-Rhin.

One Mr. Florent Marchand, from Ittenheim, from his terrace overlooking the West, reportedly saw a bright object "that had nothing of a star as it changed position, horizontally and upward."

The witness stated that he had first thought of an illusion related to the movement of the clouds, but he had no doubt anymore when, with his binocular, he took a fixed bearing on his elbows.

The color of the luminous object reportedly alternated between the blue and the red. Less than a quarter of an hour later, the "apparatus" went towards the West to "disappear."

The observation was apparently reported by Mr. Marchand to the Gendarmerie of Wolfisheim.

67 RHIN (BAS) in Strasbourg ITTENHEIM

August 15, 1968, 11 p.m. 11:10 p.m.

F - yes

From my west-facing terrace, I saw a luminous object that was not a star, coming from the south, in the direction of Mount Saint-Odile, heading north. It moved curiously downward, forward, backward, sometimes still, continuing its progression north. It appeared round, with alternating light, prism color. At the start it was clearly oriented from south to north. Subsequently it moved away to the west. It must have had a diameter of 6 m to 7.50 m. The sighting lasted about 12 minutes.

(observation of Mr. Marchand).

Comments by Mr. Fontanié. - The object was also seen at Mount Saint-Odile, Obernai, Wasselonne. The air base A. R. 124 did not detect anything on the radar and however the object remained several hours in a radius of 30 km approximately. There are many geological faults in this area. Approximate route: St-Odile, Obernai, Marlenkeim [sic, Marlenheim], Wasselonne to Sarrebourg.

Mr. Fontanié and many others shall be apologized to for the delay in their transmissions, unfortunately for lack of space. We keep thinking about it, it is a real headache for us.

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 there was a sighting on August 15, 1968, in Ittenheim in the Bas-Rhin reported in the Sélestat issue of Les Dernières Nouvelles d'Alsace for Tuesday, August 20, 1968.

At 11 p.m., Mr. Florent Marchand of Ittenheim saw from the terrace overlooking West a luminous object that was not a star because it changed position, horizontally and upward.

Christian Valentin quotes:

"I first thought it was an illusion related to the movement of the clouds, but I had no doubt when with my binocular I took a fixed bearing on my elbows. The color of the luminous object alternated between blue and red. Less than a quarter of an hour later, the vehicle sped toward the West to disappear."

He indicates that the observation was reported to the Gendarmerie of Wolfisheim by Mr. Marchand.

There is a case located in Ittenheim in Claude Poher's computerized file, but taking place in 1974 - in any event in the version available to me.

There are significant differences between the version found in the Press of the time by [cvn2] and the version given by [lcn1], for example on the movement.

That evening, the star Arcturus was visible in the heaven there, in the West (283°), low on the horizon (14°), with an apparent magnitude of 0.05. In the list of the brightest stars in visual appearance from Earth, Arcturus is just the third - the Sun being excluded.

The witness first thought of a star; which suggests that it was at least a little like a star. A low star may appear to have changing colors, and make small movements caused by the disturbances in the atmosphere. The binocular, with elbows support, is not likely to cancel that movement, but rather to enhance its appearance.

I obviously cannot guarantee that this witness saw Arcturus, but the low strangeness of the observation makes me strongly doubt that he saw an alien spaceship.


Possible star, Arcturus.
