Case of Mulhouse, on August 19, 2012:

Case number:

ALSACAT-2012-08-19-MULHOUSE-1

Summary:

On August 20, 2012, a certain Alexander Nest published a video on Youtube titled "UFO/UAP Mulhouse August 19, 2012."

The video shows 57 seconds of a flashing light and nothing else, the normal sound track was replaced by "Woo woo" music.

His (alleged) observation report merely states: "Unidentified Aerospace Phenomena (UAP) observed above Mulhouse at 3:50, August 19, 2012... No idea what it could be!"

A friend commented: "The flashing light of the motorcycle."

UFO/UAP in Mulhouse on August 19, 2012

Alexandre Nest

Published on August 20, 2012

Unidentified Aerospace Phenomenon (UAP) observed above Mulhouse, at about 3:50, on August 19, 2012... No idea about what that might have been !

Discussion:

The "witness" is sporty, he seems interested in motorbikes. Six comments added by a friend or colleague do not relate to the video, except for one that simply says: "The flashing light of the motorbike."

The normal soundtrack one would expect for a real UFO sighting was replaced by a "scary music" soundtrack.

Luminosity and contrast enhancements on images from the video Unfortunately reveal no detail that would betray the presence of a motorcycle or something like that.

This is obviously not positive proof of the contrary either: digital video, highly compressed, lose such details on the image parts that appear without details anyway.

Evaluation:

Probable innocent hoax, motorbike light.
