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.

Glowing objects above Colmar, Alsace 3/9/2012 07:15 p.m.

Good evening,

I observed on 3/9/2012 at 07:15 p.m., 2 glowing objects above Colmar in Alsace, going from the north to the south, average speed. You would have sais a plane on fire... But a 2nd objects on the same trajectory than the first appeared 3 seconds after the 1st...

Did someone observe this phenomenon ??? I filmd it with my IPhone if needed...

Thanks for your answers .



This happens at nightfall, the night was complete just 10 minutes later.

Since the mid-2000s, it is very common to release Chinese lanterns in Alsace, at wedding parties for example.

I am unable for now to "scientifically prove" that this observation is explained by Chinese lanterns, but I do not think anyone could prove that this was something alien or something paranormal. The sighting report, quite sketchy, without position, duration, sizes, color, etc., opposes nothing to an explanation by Chinese lanterns.
