Summary

An unidentified object was observed in the Atlantic on December 17, 1961. A mysterious object resembling a satellite was seen moving eastward. The sighting was made from the ground and no photographs were taken. Although it was considered possibly a balloon, the most likely conclusion is that it was Echo I, a satellite in orbit. No additional information was available, but the object coincided with the location of Echo I at that time.
