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 Logelheim, on August 1, 1996:

Case number:

ALSACAT-1996-08-01-LOGELHEIM-1

Summary:

On August 1, 1966, in northern and eastern France at least, there were a few dozen testimonies generally located around 9:30 p.m., typical of a re-entry into the atmosphere of space debris.

Through the GEIPAN website, in 2017, it can be seen that one of the sighting locations was Logelheim, that there had been a Gendarmerie report on the testimony; but as the cases of that moment are gathered in a national case file and that the numerous reports of the Gendarmerie are anonymized both for the names of the witnesses and the places, I cannot for the moment identify the Gendarmerie report corresponding to the observation in Logelheim.

The synthesis of the case by GEIPAN however allows us to see that at around 9:00 or 9:30 p.m. that day, a woman in her 40s saw in the sky a fast green ball, "1m long by 20cm high" (which is no longer a ball, probably involving a trail), silent, which she had watched until she lost sight of it.

ATMOSPHERIC REENTRY — NATIONAL (FR) 08/01/1996

SUMMARY

Probable observations of an atmospheric re-entry.

DESCRIPTION

On the evening of August 1, 1996, many witnesses observed the very rapid passage of a very luminous white ball with a yellow and green trail. The luminous phenomenon lasts about thirty seconds. It is described in the same terms from Cantal to Alsace. The times indicated differ a little but the phenomenon seems to have occurred between 9:30 p.m. and 9:45 p.m. with a movement towards the North-West.

This large-scale phenomenon, seen by many witnesses in eastern France, is probably an atmospheric re-entry.

Note: the GEIPAN publishes numerous reports from the National Gendarmerie relating to these observations on the evening of August 1, 1996; but as all the place names are suppressed, it is not possible to reconcile these proceedings with the corresponding place of observation.

[Ref. jbu1:] JEROME BEAU:

Thursday, August 1, 1996 at 9:30 p.m. to 45 A very large number of witnesses observe the very rapid passage of a very luminous white ball with a yellow and green trail. The luminous phenomenon lasted about 30 s and is described in the same terms from Cantal to Alsace. The phenomenon seems to have moved towards the northwest.

This large-scale phenomenon, seen by many witnesses in eastern France, is probably an atmospheric re-entry.

Discussion:

Map.

On May 5, 1996, the Russian automated and unmanned logistics spaceship "Progress M-31" was launched from Baikonur in Kazakhstan by the Roscosmos agency using a Soyuz-U rocket, to bring cargo to the Russian space station MIR, which was done successfully. It was deorbited at 19:44 UTC, then re-entered and burned in the atmosphere on August 1, 1996 until 20:33 UTC i.e. 09:33 p.m. local time in Alsace.

Below: Progress M52, similar to Progress M31.

Progress M52.

The sources are numerous, see for example planet4589.org/space/gcat/data/derived/launchlog.html or en.wikipedia.org/wiki/1996_in_spaceflight

The most complete data I had (below) was on space.kursknet.ru/cosmos/english/cargoes/prm31.sht

Screenshot.

Unfortunately I have not yet managed to obtain its reentry trajectory.

Evaluation:

Space junk reentry.
