ALSACAT:

As its name suggests, 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 Osthoffen, on September 3, 2005:

Case number:

ALSACAT-2005-09-03-OSTHOFFEN-1

Summary:

"Mr. L." or "M. L" had reported to the Alsatian ufology group SPICA that the day before, on September 3, 2005, at about 09:30 p.m. in the village of Osthoffen, Bas-Rhin, in the company of twenty people, he had witnessed the passage of a luminous "dot"; which he considered a priori not "classic".

He said that its height seemed significantly larger than that of a satellite, its size like a very big star. Its light was predominantly white, very bright, not blinking, with the same intensity from the beginning to almost the end of the observation that lasted about 1 minute 30 seconds.

The speed was apparently quite low, certainly slower than that of a satellite; the movement was in straight line, the altitude seemed constant but impossible to determine precisely even though it gave the idea that it was much lower than the altitude of satellites, and as if it was "under" the stars. There was no noise.

The witness noted that all the other witnesses had also found that this phenomenon did not seem to match any classical explanation of the satellite, airplane, meteorite types etc. He wondered whether other people had seen this phenomenon.

Following this report, the SPICA association had contacted the witness, asked for some clarification on elevations and headings and on September 17, 2005, they published the explanation: it was a passage of the International Space Station, whose trajectory matched what was described.

The ISS appeared in the Osthoffen sky at 09:26 p.m. at a 10░ elevation in the west-southwest, to pass over the witnesses at 09:29 p.m. at an elevation of 84░ in the North Northwest, and was out of sight at 09:31 p.m. at an elevation of 20░ in the North-East. Its magnitude was 0.8.

SPICA noted that this passage was also seen by someone in Haute-Savoie.

Title : Luminous dot moving from West to East.

Message : Hello, Last night 09/03 at 09:30' p.m. (I admit not to remember the exact time) in the village of Osthoffen - Bas-Rhin - in the company of about twenty people, I have witnessed the passage of a luminous "dot" light apparently not "classic"

"size" significantly greater than that of a satellite (... a very big star, to try to find a comparison);

predominantly white light, very bright, not blinking, the same intensity from the beginning to almost the end of the observation that lasted about 1 minute 30 ';

quite low speed (seemed slower than a satellite to me) ;

straight line displacement;

altitude, seemingly constant, impossible to assess very precisely, but it seemed much lower to us than that usually "observed" for a satellite (to make another comparison, this dot was moving to our eyes "under" the stars... I know, this is not necessarily easy to understand);

total lack of noise;

Note that all other witnesses also found that the "phenomenon" did not seem to correspond to a classical explanation of the satellite, airplane, meteorite type...

Please, did other people see this phenomenon?.

Remaining available to you.

SPICA Association

Sept. 17, 2005

Following the testimony of M. L: of his observation of September 3, 2005, at 09:30 p.m., the SPICA Association contacted the witness to check a few more details such as the angular elevation and the appearance and disappearance directions of the phenomenon.

According to the statements of the witness, the phenomenon appeared above the Scharrach and disappeared towards Strasbourg. The phenomenon passed above their heads, and they were able to observe the phenomenon for a very long time.

Following this information, we were able to establish that the phenomenon that these witnesses observed was the ISS (International Space Station), which appeared in the sky of Osthoffen at 9:26 p.m. at a 10░ altitude and West-Southwest, to pass over their heads at 09:29 p.m. at a 84░ altitude in the North-West and disappear at 9:31 p.m. at 20░ elevation in the North-East. Its magnitude was 0.8

M. P. has also seen this phenomenon, although he is in the Haute Savoie. Not knowing his place of observation, we took it as the Annemasse city. ISS was also there at 9:26 p.m. observable at 10░ in altitude West, rising to a 53░ elevation in the North Northwest at 09:29 p.m. and disappear at a 14░ elevation at 9:31 p.m. in the North East. The magnitude was there only 0.1.

We thank the witness to have contacted us, only way to find a possible explanation for the observed phenomenon.
