No. 55: Jan-Feb 1988
We wish we could pass along more data on this phenomenon. The totality of our information resides in two sentences mentioning an observation by the crew of the Soviet spacecraft Mir: "The crew reported seeing an unexplained ocean phenomenon, 'powerful concentric waves going out in the midst of a serene sea.' The cosmonauts did not report where they saw the waves but said the circular features were many miles across."
