ALSACAT:

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 Schiltigheim, on June 5, 2015:

Case number:

ALSACAT-2015-06-05-SCHILTIGHEIM-1

Summary:

A witness reported on August 17, 2015, using the form intended for this, his observation to GEIPAN, the official group in charge of "Unidentified Aerospace Phenomena" within the Centre National d'Etudes Spatiales.

He explained that on June 5, 2015, in Schiltigheim, he was unpacking boxes following his move, when he took a break sitting on his unglazed balcony, located on the 4th floor of his building.

Looking at the landscape, he saw at 9:10 p.m. while it was still daylight two "phenomena (objects I suppose) of round shape and dark color, probably black. They did not appear, they must have already been there."

He indicates that the shape was spherical to the naked eye, maybe rhombus, the color looked black, maybe whitish in the middle. There was no trail or halo. He estimates the distance as 700 to 1200 meters.

One seemed rather stable, while the second flew in arcs of circles of irregular amplitudes with the first object as the center.

The movement was very slow, he didn't notice this movement right away. He didn't hear a sound despite the quiet in the streets.

Remaining calm, he took his "Iphone 6" to film.

He was expecting a spectacular event, a light, a change of direction, a disappearance. But as the phenomenon did not change, he put his phone on the edge of the balcony, still filming.

He recorded 20 minutes of video in two videos.

After 20 minutes, he could no longer see the second object, as both seemed to lose altitude and disappear behind the buildings.

He then decided to stop filming and take his car to approach them. From the street, they were hidden by buildings and it took him a few minutes because of the traffic and traffic lights to get into Strasbourg.

Arrived around the (supposed) place, he found nothing; but it was difficult to see much of the sky from below. Arrived near the European Parliament, he decided to return home.

He specified that it was not his first experience of this kind, and that he had thought in the first minutes it was hot air balloons, "but neither the size nor the trajectory corresponded." He thought of drones but the shapes and the time spent in flight surprised him; he indicates not to give up understanding what it was.

He indicates that he has no definite opinion on the subject of UFOs, but that the fact of never finding an answer to the incredible observations he had made before forces him to be open to all sorts of hypotheses.

The GEIPAN asked him for additional information; he indicated that he was 30 years old, a supervisor with a "Bac +2" study level; that his previous observations had more strangeness.

Taking measurements regularly on the images of the two videos, the GEIPAN was able to approximately trace the apparent trajectories for the witness of the two unusual shapes. This revealed that the idea that one of the shapes revolved around the other was an illusion: "In fact, the two seem to follow similar paths, globally drifting and descending, apparently linked to local air currents." And that "Everything suggests that they are objects carried by the wind."

Studying the hypothesis of hot air balloons or gas balloons which appeared to be very plausible, a search for possible flights was undertaken; GEIPAN did not find any event of this type in France, but found that a competition took place from June 3 to 6 less than 80km from Schiltigheim and, what is more, almost in the observation direction. This was the "Horb Neckar Balloncup 2015" which took place in the town of Horb am Neckar, Baden-Württemberg, Germany.

But checking made with the organizer revealed that these hot air balloons did not approach within 40 km of the border, they had all remained east of Freudenstadt in Germany.

However, this research also revealed that tourist flights, first flights, are regularly carried out from two very close German sites, by several companies. There is a starting point from Kehl, adjoining Strasbourg on the other side of the Rhine, ~5km from the witness to the East-South-East, and another starting spot in Offenburg located ~20km to the South East. These two spots are located in the direction of the observation made by the witness.

Unfortunately, attempts to contact these companies by email did not help, as some responded negatively and others did not respond. GEIPAN thinks that these German companies are not very sensitive to the official nature of the French GEIPAN investigation.

GEIPAN classed this observation as of class "A", explained by hot air balloons.

SCHILTIGHEIM (67) 06/05/2015
Observed on: 06-05-2015
Region: Alsace
Department: Rhin (Bas)
Class: A
Summary: SCHILTIGHEIM (67) 06-05/2015. Long observation of the presence of two dark shapes in the clear sky of which one of them seems to turn turn the other: observation of hot air balloons.
Description:

On June 5, 2015 at 9:10 p.m. a witness observed from his balcony on the 4th floor the presence of two phenomena of round shape and dark color in the clear sky. The first UAP seems rather stable, the second moves slowly in an arc of a circle with the first object as its center. The witness films the phenomenon for a long time then decides to take his car to approach but loses sight of the objects (the witness's videos will be posted later on the site following a momentary technical problem). Only one testimony is collected.

The shapes discernible on the videos are largely reminiscent of two hot air balloons (see gas balloons) whose basket would not be optically separated from the balloon due to the distance. The double body aspect (balloon + basket) is reinforced by a radiometric analysis (specialized software IPACO). The two partially reconstructed trajectories (from the video and the ground marks which appear there) are quite similar except for a loss of angular height of one of the two forms. These trajectories can at some point give the illusion (witness's perception) that one shape moves around the other. These trajectories evoke those of objects carried by the wind, with a constant drift to the left of the witness. The drop in altitude of the two forms is consistent with the need to land before nightfall (according to regulations). See the investigation report.

It was not possible to finalize the exact identification of the devices originally, however a large majority of the descriptive parameters from visual observation and from the videos converge perfectly towards this very simple and plausible explanation. The probability of a flight from Kehl (or even Offenburg) is high. Indeed, there are tourist flight companies in this sector located in the direction of the observation and at a distance compatible with the observed size of the hot air balloons on the video.

The strangeness is therefore very weak and whereas there is only one witness, the consistency remains quite strong because the videos confirm his observation and allow a very objective approach of the observed phenomenon.

Consequently, the GEIPAN classifies this observation in A: observation of hot air balloons.

Madam, Sir,

You were a direct witness, on French territory, of an aerospace phenomenon that intrigued you and you want to understand what you saw.

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

- The questionnaire is individual and must be completed by the direct witness

- The questionnaire should only concern one observation at a time

Your testimony is crucial and perhaps unique. It will consist of giving an account of your observation, answering specific questions, making drawings and sketches or attaching photographs to further refine your description.

It is imperative that you follow the instructions mentioned at each step so that we can gather as much information as possible about the observed phenomenon. You should not be afraid to tell us or feel ridiculous, we are used to collecting this type of testimonies.

The conclusions of our investigation will be communicated to you personally. Once anonymized, your testimony will be published on our website (www.geipan.fr), "Case research" tab in the menu bar.

We thank you in advance for your contribution to our work.

The head of GEIPAN

IN ACCORDANCE WITH LAW N ° 78-17 OF 6 JANUARY 1978 RELATING TO COMPUTING, FILES AND FREEDOMS, AND DECREE N ° 78.774 OF

Your observation

We will ask you to provide as much information as possible about your observation. The most important thing is not to omit anything: it is often the details that allow investigations to be resolved. So don't hesitate to give as much information as possible, even if your memories are incomplete or certain elements seem unimportant to you. If you are not quite sure of a particular detail, let us know your doubts, but, again, do not leave anything out. We need to be able to visualize everything you have seen, as if to remake the film of your observation.

Use the end of this page to recount your sighting and continue on loose paper as much as you want:

Your free observation story:

on June 05, 2015, I was unpacking cardboxes following my move in.

I made a pose [sic, pause] and sat down on my terrace (Dutch balcony).

I sat down and opened a packet of crisps. I then look at the landscape when I perceive two phenomena (objects I suppose) of round shape and dark color, probably black. They did not appear, they must have already been present.

One had a rather stable movement while the second made arcs of circles with the first object as the center. (with irregular amplitudes)

The movement was very slow. I didn't notice the rotation right away.

I didn't notice any noise despite the calm in the streets.

I kept my cool and took my iPhone 6 to film

I expected a spectacular event, a light, a change of direction, a disappearance. Since the phenomenon was not changing, I put my phone on the balcony ledge (still filming).

I waited and I ate some crisps that were next to me. (buzz sound on the video).

So I filmed 20 minutes of the phenomenon in 2 videos.

After 20 minutes I could no longer see the 2nd object because both seemed to lose altitude and disappear behind the buildings.

So I decided to stop filming and take my car to approach them.

I couldn't see them from my street because of the size of the buildings and I took a few minutes because of the red lights and the traffic (I entered Strasbourg).

Arrived around, I did not find the phenomenon. It was difficult to see a large area of the sky from below.

Arrived near the European Parliament. I decided to go home.

Please provide all the information requested.

What were your occupations just before your observation?

Just before the sighting, I was emptying cardboxes following my move in.

Reconstruction of your observation

In order for us to be able to reconstruct the "movie" of your observation, we must have as much information as possible. 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:

  1. Take a picture of the environment as it was during the phenomenon, as if the camera were your eyes when observing. Feel free to draw what you observed directly on the photos.
  2. Make one or more sketches of your observation (see next page) from your point of view, including the environment. Give as much information as possible to allow us a good understanding of the scene.

    You are entirely free from the sketches that you send us. But color accuracy is important, especially if the level of contrast between the observed phenomenon and the environment is low. Try to be as precise as possible, even if it means writing on the sketch.

    No drawing skills are necessary. The main thing is to make us understand what you saw in a schematic way. You can use the following page for this purpose.
  3. Reconstruct your observation on one or more planes. If you can, this is to present your observation from a top view. To do this, you can print a map of your observation location on Google Map (http://maps.google.fr) or Geoportail (http://www.geoportail.gouv.fr/accueil) and record your different positions there, and the directions of observation.

How to "dress" a photo or a card with your comments?

If you are used to using drawing or image editing software (Photoshop, GIMP, Illustrator, etc.), we recommend that you use these tools, then we send a file in jpg, png or pdf format.

If you cannot access this type of hardware, print a map of the places 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.

What now?

Describe the emotions you felt during and after the observation:

I did not feel any particular emotions during the observation.

I was very calm.

Even strangely very calm eating crisps.

However, before the second phenomenon completely disappeared from my sight (end of the second video), I took my car to take a closer look,

Having found nothing (difficult traffic and building hiding the sky in the city) I felt frustrated and annoyed not being able to have filmed closer.

What did you do after your sighting? Did you talk about it? How did your interlocutors react? Did you do any research to understand what you saw?

I did not mention it immediately, then to a friend who reacted by not seeing an explanation.

It surprised him.

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

I thought in the first few minutes of balloons (Montgolfier), but neither the size nor the trajectory matched. Then to drones, but the shapes, the trajectories and the time spent in the areas amaze me. I don't give up on understanding.

Before your observation, how interested were you in strange aerospace phenomena? Did you have a specific opinion on the subject? Which ? What were you basing it on?

This is not my first experience like this and it is by far not the most incredible that I have seen. However, it is the only one that I have been able to immortalize on video.

I think that's why I remained very calm during the sighting.

I have no specific opinion on the matter. However, the fact of never finding an answer to the incredible observations that I have been able to make forces me to be open to all is beyond hypothesis.

Did this observation change your view of unidentified aerospace phenomena? If so, explain what you think now:

Despite this observation, I am and I remain very down to earth, looking for concrete and scientific explanations for my observations.

Do you think that science will provide an explanation for your observation?

Yes I think so, maybe drones, maybe other things I haven't thought about yet.

But like a testimony, an explanation must be proven.

INVESTIGATION REPORT

SCHILTIGHEIM (67300) 05.06.2015

OBSERVATION CASE

1 - CONTEXT

On 06/10/2015, GEIPAN received an email from the witness who sent 2 video files, 2 situation maps as well as the completed questionnaire relating to the daytime observation of a suspected UAP.

GEIPAN replied to it on 10/07/2015 asking for details relating to missing information in the questionnaire.

2- DESCRIPTION OF THE CASE (according to the elements received)

Witness T1: source: Questionnaire.

Date: June 05, 2015

Time: around 9:10 p.m. (HL) or 7:10 p.m. (UT) Duration: ~ 20 minutes

Location: Schiltigheim (67300).

Witness: 30-year-old male. Control agent. (Bac +2 level of study).

...On June 05, 2015, I was unpacking cardboxes following my move in. I did a pose and sat down on my terrace (Dutch balcony). I sat down and opened a packet of crisps. I then look at the landscape when I see two phenomena (objects I suppose) of round shape and dark color, probably black. They did not appear, they must have already been present.

One had a rather stable movement while the second made arcs of circles with the first object as its center (with irregular amplitudes).

The movement was very slow. I didn't notice the rotation right away.

I didn't notice any noise despite the calm in the streets.

I was calm and took my Iphone6 to film.

I expected a spectacular event, a light, a change of direction, a disappearance. Since the phenomenon was not changing, I put my phone on the balcony ledge (still filming).

I waited and ate some crisps that were next to me (noise on the video).

So I filmed 20 minutes of the phenomenon in 2 videos.

After 20 minutes I could no longer see the 2nd object because both seemed to lose altitude and disappear behind the buildings.

So I decided to stop filming and take my car to approach it.

I could not see them from my street because of the size of the buildings and I took a few minutes because of the red lights and the traffic (I entered Strasbourg).

Arrived around, I did not find the phenomenon. It was difficult to see a large area of the sky from below. Arrived near the European Parliament. I decided to go home. ...

- The place and date are known with precision.

- It was still daylight (setting sun). The weather was clear and the blue sky clear (clouds in the distance).

- The phenomenon seemed to be present in the sky before T1 saw it.

- It seems quite far (in the order of a km).

- The observation time is quite long (~ 20 min).

- The UAP appears to consist of two distinct but very similar and apparently independent forms.

- The moves of the UAP are very slow, with a gradual disappearance of one of the two forms, apparently hidden by a building.

- Angular height of appearance: low.

- Angular height of disappearance: very low.

- Sinuous and generally descending paths.

- Observation direction: East-South-East.

- Displacement in azimuth estimated by T1: from 30 to 45 °, towards the north (from right to left).

- No trace remains.

- No perceived noise other than ambient noise (city).

- No particular effect.

- T1 attempted to approach UAP by car but was unsuccessful.

- No other known witnesses.

- T1 claims to have made other (weirder) sightings in the past.

- T1 filmed the UAP with his Iphone6 over a cumulative duration of close to 18 minutes, which allowed him to stay calm (since he would have proof).

- T1 once thought that it could be hot air balloons and then drones but rejected these possibilities on the one hand because of the size, on the other hand because of the trajectory and the autonomy flight.

3- REMOTE INFORMATION SEARCH

New elements collected remotely:

Precise location of the witness:

It is confirmed by a third party (residing in the greater Strasbourg area) that hot air balloons are sometimes observed in the sky over the Alsatian capital, but this third party has no particular memory for this date (neither does his family ).

Two important elements of the urban landscape, clearly visible on the videos, are identified, namely:

- The FR3 Alsace television tower (to the left of the observation field).

- The fireplace in the former Schutzenberger brewery (to the right of the observation field).

A difficulty arises in accurately locating the location of the witness since the geolocation provided by Géoportail or GoogleMaps from the postal address is often only an approximation.

The precise location of the witness is found thanks to various cross-checks. Azimuth, altitude and angular height readings are now available.

Observed shape:

The shape of the two "presumed craft" not appearing to be perfectly circular, a video image capture, carried out with the IPACO software, allows to have both visual and radiometric confirmation (see appendix 4).

Trajectories:

Measurements taken regularly on the images of the two videos made it possible to trace approximately the apparent trajectories (seen from the position of T1) of the two unusual shapes.

(see appendix 3).

They reveal that T1 was deluded into thinking that one of the shapes was slowly spinning around the other. In fact, the two appear to follow similar trajectories, broadly drifting and descending, apparently linked to local air currents.

Everything leads us to believe that these are deices carried by the wind.

As the apparent sizes do not seem to vary appreciably between the beginning of the first and the end of the second video, it is plausible to deduce that the distance to the witness varied little, therefore that the slow observed drift took place globally in a south-west to north-east direction, i.e. perpendicular to the direction of observation.

Distance:

No reliable benchmark allowing to objectively estimate the Witness-Uap distance, it is from the apparent size (determined thanks to the video) and the various common sizes of the hot air balloons that the distance is therefore evaluated (for this hypothesis).

Altitude:

Based on these possible distances (depending on actual size), it is possible to deduce the maximum altitude (start of observation). Angular height < 8.7 °

If diameter = 6 m distance: 6.875 km Altitude: 1052 m
If diameter = 10 m distance: 11.459 km Altitude: 1753 m
If diameter = 15 m distance: 17.187 km Altitude: 2630 m
If diameter = 20 m distance: 22.917 km Altitude: 3507 m

These altitudes are perfectly compatible with the aerostats hypothesis.

Meteorology:

The meteorological data collected (see appendix 5) show that the conditions were favorable for aerostats flights. (Stable temperature, stable pressure, very low wind, sunset, no precipitation). The movements observed are not perfectly compatible with the directions of the wind on the ground but it is important to note the fact that on the one hand this direction is very changeable between 9 p.m. and 10 p.m. and that on the other hand the wind at altitude can differ significantly, wind on the ground, especially during turbulence associated with sunset.

Indeed, local turbulence can easily prevail over a remarkably weak prevailing wind.

Aerostats flights:

Since the hot air balloon / gas balloon hypothesis appears very plausible, a search for possible flights is undertaken.

Despite all the contacts made with the French aerostation structures (balloon level), it was not possible to identify a flight of two devices likely to account for the sighting.

However, the UAP evolution area being a border (Franco-German border at 4.7km in the mean observation azimuth 115°) it may very well be that German balloonists are at the origin of such flight. All the more so since this activity is highly developed across the Rhine.

An additional research relating to potential flights located across the Rhine is therefore undertaken.

A first discovery reveals that a competition takes place from 03 to 06/06 less than 80km from Schiltigheim and, what is more, almost in the observation azimuth. This is the "Horb Neckar Balloncup 2015" which takes place in the city of Horb am Neckar (Baden-Württemberg).

The idea is therefore put forward that two of these hot air balloons could have approached the Franco-German border at the level of the town of Offenburg.

Thanks to an exchange of emails with an organizer of this competition, this track had to be ruled out.

Verification made by this kind collaborator, the hot air balloons did not approach within 40 km of the border, the rules of this competition having been defined to avoid any risk of landing in the Black Forest. The 15 balloons in competition all remained east of Freudenstadt (Germany).

However, this research also revealed that tourist flights (notably tourists first flights) are regularly carried out from two very close cross-border sites, by several companies. On the one hand a departure from the town of Kehl (border town with Strasbourg) which is only ~ 5km from the witness in the East-South-East, on the other hand another departure from the town of Offenburg located ~ 20km to the South-East. These two places are located in the direction of the witness's observation.

Attempts to contact these companies by email failed to confirm this hypothesis as some responded negatively and others did not. These are German companies for which the official nature of the GEIPAN investigation may have less weight than in France.

5- CONCLUSION

The shapes discernible on the videos (see appendix 4) are largely reminiscent of two hot air balloons (or even gas balloons), the basket of which would not be optically separated from the balloon due to the distance. The double body aspect (balloon + basket) is reinforced by a radiometric analysis (specialized software IPACO). The two partially reconstructed trajectories (from the video and the ground marks that appear there) are quite similar except for a faster loss of angular height of one of the two forms. These trajectories can at some point give the illusion (witness's perception) that one shape revolves around the other. These trajectories evoke those of objects carried by the wind, with a constant drift to the left of the witness. The drop in altitude of the two forms is consistent with the need to land before nightfall (according to regulations).

It was not possible to finalize the exact identification of the devices originally, however a large majority of the descriptive parameters from visual observation and from the videos converge perfectly towards this very simple and plausible explanation. . The probability of a flight from Kehl (or even Offenburg) is high. Indeed, there are tourist flight companies in this sector located in the direction of the observation and at a distance compatible with the observed size of the hot air balloons on the video.

The strangeness is therefore very weak and if there is only one witness, the consistency remains quite strong because the videos confirm its observation and allow a very objective approach of the observed phenomenon.

Consequently, this observation should be classified in A: Observation of hot air balloons

Graphic reconstruction of the trajectory of the NAPs

Reconstruction of the evolution of the UAPs on the first part of the first video, over a period of 5:30 minutes and in a step of 30 seconds.

Variations in the orientation of the iPhone have been compensated for by tracking relative to the antenna.

Then, simultaneous variations in orientation and zoom, combined with de-focusing prevented the continuity of these trajectories from being ensured

Two other parts of the movement, produced in an almost similar fashion, are presented on the following pages.

Annex 03b

Graphic reconstruction of the trajectory of the UAPs

The trajectories continue with a continuous drift to the left. Here again, it is clear that the two UANs undergo simultaneous and quite similar variations as was already the case on the first part of the trajectory. This irresistibly suggests evolutions of a lighter-than-air that undergoes winds or (thermal) air currents.

After a rather chaotic and hardly usable end of video 1, a second video allows the reconstruction to continue. The end of the filmed trajectories remains consistent with the previous phases, but again showing a loss of altitude (and / or distance). One of the UAPs (yellow) disappears before the other (position 29) in the ~ 115.75 ° / NG azimuth, hidden by a building.

Annex 04

Shape of the UAPs

Video capture under IPACO (V3.96w) of a shape with vertical radiometric cut

This radiometric cut confirms the visual impression obtained by a magnification of one of the shapes recorded on the videos.

It clearly appears that the shape initially perceived as spherical is in fact elongated downwards in the form of a point. This seems to correspond perfectly to the shape of a hot air balloon or a gas balloon whose basket and lines would add to the spherical shape of the balloon.

Summary of the day

Extract data between 1 p.m. and 11 p.m.

According to these Météociel data, it appears that there was a southerly wind (close to the ground) since the beginning of the afternoon which passes into the south-eastern sector at the start of the observation, becoming very changeable by the continuation to gradually move towards the northern sector (Cf. graph).

This wind was weak because less than 6km / h (7km / h in gust).

The temperature of 29.4 ° C at the start of the observation gradually decreases (sunset) while the humidity increases slowly. Visibility is around 40km.

No rain.

The data collected via the Météo60 Website seem to confirm the data from Météociel, i.e. a weak wind (close to the ground), less than 6 or 7 km / h which gradually passes from the South-East sector to the North sector, a temperature of ~ 29 ° C which slowly decreases as the humidity% increases slowly (sunset) and the pressure remains stable. No rain.

Note:

It is important to consider that the wind conditions at altitude may be different from those measured at ground level.
