A ufology blog from the South of France received on Sunday, March 15, 2015, a testimony of an observation made at that date at around 08:45 p.m., on what many other witnesses described as the high-speed passage of a luminous green ball with a white trail.

The testimony came from Bartenheim-la-Chaussée, it is unclear whether the witness thought he was seeing a UFO or understood that it was a meteor.

15/03/2015 - 8:45 p.m. - Green Glow in the East of France!


Sunday, March 15, 2015, around 08:45 p.m. we have several witnesses reporting they observed the high speed passage of a bright green ball with a white trail in eastern France.

One of the witnesses was in the Haute-Saône (70), the other in Alsace in the Haut-Rhin in Bartenheim-la-Chaussée (68870). There are many witnesses (see comments below).

This phenomenon is typical of an atmospheric reentry: a meteor or debris whose passage ionizes the air, offering this amazing and beautiful green color.

Same phenomenon seen at 9 pm above La Walck (Bas-Rhin)

Seen at 08:45 p.m. in Marckolsheim (67)!!! meteorite observed in the East, its direction North=>South (Lahr=>Freiburg). It reminded me the one in 1990 when the light was such that, one could see his shadow like in full daylight...
