Two luminous balls over the ocean at Saint-Jean-de-Monts

Summary

On August 12, 2006, a witness in Saint-Jean-de-Monts observed two luminous balls over the ocean. They moved at low altitude with faint brightness, but within seconds their intensity surged dramatically before they vanished. The testimony did not reach GEIPAN until 2008 and was not corroborated by other observers. The description is reminiscent of flying lanterns, but the lack of precise details prevents a definitive identification. Classification C: a conventional explanation is neither ruled out nor confirmed.
