Strong Magnetic Field Detected Following a Sighting of an Unidentified Flying Object

Following the brief sighting of an unidentified flying object in Gulf Breeze, Florida in September 1992, investigators made an area search using a fluxgate gradient magnetometer and found a strong magnetic field gradient, indicative of a strong source of magnetic field, which appeared to be at or above the tops of some trees near a small pond. Three circles of depressed grass were found in the bottom of the shallow pond. This paper discusses the sighting, the area search, the circles and the field gradient measurements. An estimate of the field strength is presented and compared with magnetic effects associated with other sightings.
