Bright light and fallen tree in Ambernac

Summary

On a foggy October 1983 night, a resident of Ambernac was alerted by his dog's agitated behavior. Through the window he saw an intense light the size of a tractor wheel moving slowly before disappearing behind a group of poplars. The next day, a 25-meter tree was found broken at eight meters high, with a dual fracture—a clean break followed by a two-meter crack.

Analysis revealed the tree had been weakened by fungi over a long period, its outward appearance intact until its balance gave way under minimal pressure. Prevailing winds also contributed to the deterioration. One hypothesis suggests the light may have come from bioluminescent organisms released when the trunk broke, which would explain the glow the witness saw. The case is notable for the temporal coincidence between the light and the tree's collapse.
