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.

09-06-2018 - (Dep.67) - Luminous balls

Date: 06-09-2018

Department: 67 (Bas-Rhin)

Location: BARR

Time: 11:30 p.m.

Numbers [sic] of witnesses: 1 people

Type of observation: NL: Nocturnal Lights

Approximate duration of the observation: 1 minutes [sic]

What has been seen: luminous balls

Description of the facts:

3 perfectly aligned luminous balls advancing in parallel and very slowly silently and at equal distance from each other before disappearing behind clouds.




The very brief testimony does not allow very strong statements to be made; but it is quite obvious that the three luminous balls could have once again been Chinese lanterns.

Since 2005, the Chinese lanterns constituted the bulk of the "testimonies" which one finds on Websites about UFOs and publishing primarily such "testimonies" brought via the web and whose only treatment is in general the publication, without any information on a possible cause, without investigation or research.

As these miniature hot air balloons are generally launched at private or public parties, they are most often seen on Saturday evenings and during calendar holidays such as New Year's Day or July 14, between 10 p.m. and midnight. They are then generally released in clusters. But sometimes the purchaser makes a test a few days before, sometimes with only one lantern.


A Chinese lantern.
