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 Strasbourg, on March 19, 2009:

Discussion:

On March 19, 2009, space shuttle Discovery was docked to the International Space Station (ISS) for mission STS-119. Together, the two spacecraft were even brighter as the ISS usually is.

Also, on February 10, 2009, two satellites, Cosmos et Iridium 33, collided, and it was expected that from March 7, 2009 and on, 355 pieces of Cosmos, and 159 pieces of Iridium 33, would start to enter the atmosphere.

One or the other event may have been the cause of this sighting, but he information at hand is too poor to determine the cause with any certainty.

Evaluation:

Probable rentry of satellites debris.
