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 Munster, on October 22, 2013:

Case number:



A male resident of Munster filled the testimony form of GEIPAN, the official group in France in charge of dealing with the issue of UFO reports.

He reported that this very day October 22, 2013, at 10:40 p.m., he saw in the clear sky the passage from the South to the North of a dark silent object in the shape of half-dome with excrescences hanging below.

The observation of less than 10 seconds did not give him time to take a photograph.

The thing passed in front of the moon in the east, approximately at the vertical of hills located east of the city of Colmar. It was slightly larger than the apparent width of the crescent moon.

The witness had first thought of a cloud, but its shape was not that of a cloud: the object was rounded on the upper part, flat in its lower part, with parts directed downwards, "a little like huge insect legs hanging under its body." The witness provided a sketch of this thing - visible further down in this file.

The GEIPAN, according to the information provided by the witness in the questionnaire and an interview with the witness, classed this case as "B", as probably explained by a ladybug-shaped helium party balloon that escaped its owner.

MUNSTER (68) 10/22/2013

Observed on:22-10-2013
Departement:Rhin (Haut)
Summary:Observation of the silent movement S-N of a dark object in the shape of a half-cupola with protruding pendants: probable observation of the passage of a party balloon.
Description: On October 22, 2013 at 10:40 p.m., a witness looking at the clear sky is intrigued by the passage S-N of a dark object in the shape of a half-dome with pendent growths. The very short observation (less than 10 seconds) does not allow the witness to take a photograph. The silent object disappears in the darkness of the night sky.

According to the elements collected by the questionnaire and interview with the witness, the GEIPAN classifies this case "B" as probably a party balloon inflated with helium, type "ladybug", which would have escaped its owner.

Madam, Sir,

You have witnessed directly, on the French territory, an aerospace phenomenon that has intrigued you and you want to understand what you have seen.

In order to answer your questions, the National Center for Space Studies and its specialized service GEIPAN offer you a two-step approach:

  • On the website, first consult the UAPS identification guide where you may find an explanation for your observation.
  • If you have not found an explanation, complete the following questionnaire that will allow us to open an investigation.
    • The questionnaire is individual and must be completed by the direct witness
    • The questionnaire should concern only one observation at a time

Your testimony is important and perhaps unique. It will consist of telling a story of your observation, answering specific questions, making drawings and sketches or attaching photographs to further refine your description.

It is imperative that you adhere to the instructions mentioned at each step so that we can gather as much information as possible about the observed phenomenon.

You must not be afraid to tell us about it, nor feel ridiculous, we are used to collecting this type of testimony.

The conclusions of our investigation will be transmitted to you personally. Once made anonymous, your testimony will be published on our website (, tab "Case Search" in the menu bar.

We thank you in advance for the contribution you make to our work.

The head of GEIPAN

Your observation

We will ask you to provide as much information as possible about your observation. The most important thing is to leave nothing out: it is often the details that make it possible to solve the investigations. Do not hesitate to give the maximum of information, even if your memories are incomplete or that certain elements seem unimportant to you. If you are not sure about this or that detail, tell us your doubts, but, again, do not omit anything. We need to be able to visualize everything you've seen, like re-runing the movie of your observation.

Use the end of this page to tell the story of your observation and continue on free paper as much as you want:

Your free account of the observation:

Tonight, October 22, 2013, at 10:40 p.m., observing the moon in the direction of the east, I saw an object that passed between the moon and me, in the south-north direction, approximately vertical to the hills located at the east from the city of Colmar. I first thought of a cloud, but its shape was not a cloud. The object had a rounded shape on the upper part, flat in its lower part, with parts directed downwards, a little like enormous legs of an insect hanging under its body. I wanted to take a picture of it using my cellphone, but it came out of the moonlight before I could do it.

Conditions of observation of the phenomenon

What were your occupations just before your observation?

I was in my daughter's apartment on the ground floor of our house. After turning off the lights, I closed the front door. It was at this moment that I observed the sky, which was almost clear, and the moon partially hidden by what I first thought to be a cloud.

Specific address of the place of observation (street, city ...):

The observation was made from my home on the parking lot in front of the house, looking east.

Reconstitution of your observation

In order for us to reconstitute the "movie" of your observaAon, we must have the maximum amount of informaAon. Concretely this implies that we understand everything from the beginning to the end of your observation, and that we know the direction of movement of the phenomenon as well as its altitude. This step is crucial.

We offer three complementary methods:

How to "caption" a photo or a map with your comments?

If you are used to image editing software (Photoshop, GIMP, Illustrator, ...), we advise you to use these tools, then send us a file in the jpg png or pdf format.

If you can not access this type of material, print a map of the place and / or a photo, draw over it and attach it to the paper file; or scan or photograph the result and send it to us in jpg, png or pdf format.

Sketch of your observation

Use this page to draw your observation.
You are entirely free as of the development of this sketch.

NB: the shape of the moon is not exact because it is not a full moon. It showed a small crescent to the south.

And now?

Describe the emotions you felt during and after the observation:

At first none because I thought it was a cloud, then I was intrigued. I especially regretted not having had the time to take a photograph.

What did you do after your observation? Have you spoken about it? How did your interlocutors react? Have you done any research to understand what you saw?

I have not spoken to anyone yet.

I searched via the net, without result so far.

What interpretation do you give to what you have observed? Have you thought of a known phenomenon? What are the elements that justify your interpretation? If you do not know, did you give up understanding? If so, when and why?

I do not like giving up, so I will continue to search.

Before your observation, what interest did you have in strange aerospace phenomena? Did you have a clear opinion on the subject? Which one? What is the base of your opinion?

These phenomena intrigue me. In the absence of an official proclamation of those who would have the greatest possibilities of observation, it is difficult to get an idea on the matter. I have 2 opinions whose conclusions are diametrically opposed. On the one hand, I think it is unlikely that we are alone in the universe. On the other hand, I believe that distances make any contact with other civilizations impossible.

Did this observation change your vopinion on unidentified aerospace phenomena? If yes, explain what you think now:


Do you think that science will give an explanation to your observation?

On September 6, 1998, around 8 p.m. in Voreppe, in the Isère, France, a family had seen and filmed in video a similar thing. The witnesses were talking of "legs" hanging under the object, and on the video, one of the witnesses was saying, "It looks like a ladybug..." It turned out, after investigation by the SEPRA (an ancestor of GEIPAN), that it was indeed a "ladybug", i.e. a lost party balloon shaped like a ladybug. This is why GEIPAN considers that this can be the explanation for this observation, and in fact, nothing goes against it.


Probable party balloon.
