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 Mulhouse, on June 29, 2019:

Case number:



On June 30, 2019 at 11:30 p.m., a person anonymously uploaded a video from a cellphone using the "Snapchat" application to the testimonies collection section of the MUFON website.

The video was reportedly taken at Mulhouse on June 29, 2019 at 11:30 p.m.; the witness gave the title "red lights" and his report boiled down to saying: "Red lights in a circular shape moving in a diamond and a triangle".

The video shows Chinese lanterns like I myself often watched and even filmed in Mulhouse, where I live.

The MUFON case file was then copied with indication of source "MUFON" by the US Website UFO Stalker, which gives no comment or explanation; then on the blog "OVNI Paranormal" of Frenchman Christian Macé. The latter evokes as possibilities that they are Chinese lanterns, or... UFOs disguised as Chinese lanterns...

The witness gave, in French, the title "lumières roufges" ("red lights") and his report was to say: "Des lumiéres rouges en forme circulaire se déplacant en losange et en triangle" ("Red lights in a circular shape moving in a diamond and a triangle").

UFOs filmed in Mulhouse in the Haut-Rhin in France on June 29, 2019

Here I have extracted this image from the video. UFOs in Mulhouse, June 29, 2019...

Call for witnesses... Did you see these UFOs, did you film or photograph them? Your testimony interests us! Contribute to the enrichment of our heritage on UFOs... Thank you.

This was uploaded on June 30, 2019, on the MUFON English Website. This is the case Nr 101629:

The VIDEO of UFOs in Mulhouse on June 29, 2019, on the MUFON website:

Also posted on the English website of UFO STALKER. This site lists the UFO cases that have reached Mufon, details the UFO sighting and archive:


"Red lights in a circular shape moving in a rhombus and a triangle".

Also here, same case: VIDEO:

Are these Chinese lanterns, or a Chinese lantern UFO camouflage? Read in the link below, my study on UFO camouflages:



The video file information confirms the shooting date as June 29, 2019, but the time is 10:57 p.m., not 11:30 p.m.. The visual sighting may have lasted 2 minutes, the video lasted 40 seconds.

Chinese lanterns are one cause of some old tales of UFO sightings: During the "airship" wave of 1896 - 1897 in the USA, during the wave of 1972 in the US Midwest, etc.

Since these miniature hot air paper balloons can be ordered on the Internet at very low cost - they also commonly found in Alsace now in stores - there is no need anymore to take the trouble of manufacturing them yourself.

So since 2005, about everywhere and of course in Alsace, many people who do not yet know about them report them as UFOs or at least as a subject of puzzlement: "It was not planes, not satellites, not helicopters, etc...", commonly appears in the stories. Indeed they aren't.

In principle, any ufologist worthy of the title should be able to recognize a story related for sure or at least possibly to Chinese lanterns, but there are still ufologists who do not want to listen, or quibble, demanding that a guilty lantern is handed to them otherwise they want the story to remain a "UFO report".

Most of the time, I certainly cannot "scientifically prove" or provide "hard evidence" that this or that report is explained by Chinese lanterns; but I see nothing opposes it and nothing would justify to call it spacecraft from another world or who knows what else.

It is sometimes possible to find that there was, precisely at that time, in the vicinity, a release of lanterns, during a party, a wedding party, a birthday party etc. But these releases are now so usual in Alsace at least that they are not necessarily mentioned on festivity calendars.

Since 2005, they constitute the bulk of the "testimonies" of UFOs found on websites devoted to the subject of UFOs and essentially publishing such "web report"; generally the only treatment is the publication, without any information on a possible cause, without any investigation or comment.

In Alsace, such releases are especially popular now since fireworks and firecrackers, long tolerated, are now prohibited for use unless special exemptions; Alsatians therefore largely adopted the lanterns.

As these lanterns are usually released at private or public parties, they are most often seen on Saturday nights, often at wedding dates or official festivities such as the National Day or New Year's Eve, usually between 10 p.m. and midnight. They are then usually released in clusters. But sometimes the purchaser performs a "test flight" a few days before, sometimes with a single lantern.
