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.

On January 21, 2004, a meteor had flown over Belgium, and exploded over Mainz, Germany.

January 21 at 5:33 UT throughout Belgium with the exception of East Flanders, west of West Flanders and Hainaut, these regions being under the clouds.

The trajectory of the object passes over Aalst between Brussels and Halle towards Wavre, as well as over the Ardennes in the irection of Luxembourg and Germany. There remains some uncertainty regarding the final part of the path.

The fireball, probably a meteoride of twenty centimeters in diameter, disintegrated in the atmosphere over Germany, causing an intense flash of light reported by many witnesses who shared their observations with country police services.,1518,282850,00.html


Maybe someone or some people had reported a "phnomenon or even a "UFO" to the SPICA.
