ALSACAT-1996-08-01-SIERENTZ-1
Around 2002, Emmanuel Dehlinger published an electronic book on the Web in which he claimed that UFO sightings are "created" by "the military" (?) by means of various devices such as luminous balloons; in the book, he proposed a "Study of the wave of August 1, 1996" in France, in which he noted a sighting in Sierentz in the Haut-Rhin, while eliminating this case from his statistics on the grounds that it would be the same as a case in Obernai - which is not true - and while noting all the same that this "wave of August 1, 1996" could be explained by an "atmospheric re-entry" but that "this is not confirmed."
The sighting is said to have appeared in the ufology magazine Lumières Dans la Nuit #340 around 1996; it does appear in a sighting list on the web, but without any details.
In 2017, the "Groupe d'Etude et d'Informations sur les Phénomènes Aérospatiaux Non Identifiés" ("Group for Study and Information on Unidentified Aerospace Phenomena") (GEIPAN) published the French cases of August 1, 1996 collected by the National Gendarmerie, grouped together in a common file with a common explanation, that of an "atmospheric re-entry".
Their summary for the Sierentz case, which is oddly dated of August 2, 1996, indicates the time as 9:30 p.m.; there would have been two male witnesses, and it was about a green ball with a trail, silent, very fast, in descending trajectory.
I show in this dossier that these observations temporally correspond perfectly to the re-entry into the atmosphere of the Russian cargo spaceship "Progress M-31"; however, I have no information on the trajectory yet.

Etude de la vague du 1er août 1996
Cette vague se produit peut-être au cours d’une rentrée atmosphérique, mais cela n’est pas confirmé. Les cas étudiés ici sont tous ceux pour lesquels l’heure est indiquée. Même si la plupart des cas évoquent visuellement une rentrée atmosphérique, la plage horaire des observations qui s’étale sur plus de 45 minutes et les incohérences dans les directions de mouvement affaiblissent cette hypothèse.
Le détail des cas se trouve en annexe B § XXI.
On constate 5 cas (100%) d’utilisation de l’effet ECS dont 1 cas d’utilisation de l’effet EC2, soit 20%.
Le commentaire sur chaque cas est malheureusement très succinct, ce qui ne nous permet pas d’affirmer à coup sûr que l’apparition d’Sierentz (Bas-Rhin) est différente de celle observée à Sierentz (Haut-Rhin), ~89 km plus au sud. Or ces 2 cas bénéficient de l’effet ECS conjugué à l’effet ECL, ce qui est exceptionnel (1 chance sur 170). Pour éviter de compter 2 fois par erreur un cas très favorable à notre hypothèse, nous avons préféré éliminer le cas de Sierentz.
Sierentz (Haut-Rhin) 7° 28 E 47° 40’ N 22:04C -9° 10’ 310° -0° 49’ 97° ECS, ECL, EC2 J1, NC1 Round ufo. At ~89 km south of Obernai. This case is eliminated because one cannot affirm with certainty that it is different from the observation of Obernai. R Nr 340 p. 33

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.

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.

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