Ten years back I saw the lights for the first time: A greenish gleaming, flickering. The night was quieter, than the inside of a grave.
Actually they where not very bright. But: they moved!
Today I want to know it more exactly. Together with the WildWeb team I installed a light sesitive camera, which is directed toward the entrance of the cave. Up to today some few humans saw the lights, but there does not exist one single photo proof!
