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.

ALSACAT: Totally insufficient information.




On the 6th [of October 1973] in Brunstatt (suburb of Mulhouse), 6:47 p.m. - At 6:47 p.m. very exactly, several people were able to see, in the sky over Brunstatt, two UFOs, lit with an orange light, traveling towards Altkirch... and suddenly turn off one after the other. ("L'Alsace" of 11/7/73, transmitted by F.D.).

[Ref. uda1:] "UFODNA" WEBSITE:

6 November 1973 18:47

Brunstatt, Alsace, France

Nocturnal lights were reported.

Hynek rating: NL

Vallee rating: FB1

The sources are indicated as: "Delval, Pierre, Ouranos, Commission d'Etude "Ouranos", Bohain."



With the sparse information available to me for now, what could I say?

Altkirch in the the south of Brunstatt.

To the South, there was Jupiter in the sky at 192░, elevation 21░. To the Southwest, Venus at 222░, elevation 3░ 5':

Carte du ciel.

This could be the cause of the sighting, but it is not entirely convincing. Jupiter appears orange-colored, but not Venus; which is buish white. And we are told of a move towards Altikirch whereas these planets would have appeared almost motionless.

Of course, this could have been Chinese lanterns, planes, whatever...


Totally insufficient information.
