Go Back Report # 647



September 12, 1992  

Some UFOnauts have magnetic: personality . . . I guess. Anyway, one UFO appears to have "left behind" a strong magnetic field.
       On Friday, September 11; 1992, at approximately 6:20 p.m. Mrs. A., who wishes to keep her name confidential because of her position in a rather important local business, was entering the driveway at her home in Gulf Breeze when she saw to the northeast, over the roof of her house, an unusual round object with a classic "disk" shape-round like a saucer with a dome on top. It rose upward, moved toward the east a short distance while flipping over so that the dome was now on the bottom, and disappeared in the clear sky (See Sketch 3). The object appeared brownish grey at the top and bottom with a pinkish red line around its circumference. The center of the bottom seemed to be glowing. The object was at some distance and apparently had risen upward from behind her house, where there is a lawn, a pond, and trees. The total duration of the sighting was several seconds.      
       Within an hour or so the witness told a very close acquaintance, J., (who also wishes anonymity) about the sighting. He, being aware of the activities of the Gulf Breeze Research Team of Pensacola MUFON, contacted Bland Pugh and Brace Morrison several hours later, and they decided to investigate the sighting during the afternoon of the next day.

       The next morning J. decided to search the area behind the house to determine whether or not there was any trace of magnetism left by the UFO. He decided to search for a magnetic field because many years before (in 1973) he had had a UFO sighting which, in his opinion, involved a strong magnetic field. A UFO passed over his car and afterward the gauges on the dashboard, including the nonelectrically-operated oil pressure gauge, all pointed roughly toward the steering column, a shaft of magnetizable iron. He believed at the time that a strong magnetic field associated with the UFO had magnetized the steering column, causing the needles to point toward it. Unfortunately at that time he had no instrument to confirm that there was a magnetic field. But now he has a very sensitive device, a flux gradient magnetometer or "gradiometer" (model GA-52, manufactured by the Schoenstedt Corporation of Reston, Virginia), which he has used during the last ten years for searching for buried iron pipes as part of his work. Taking his gradiometer, he walked around the area behind the house (See Map 3). While walking along the north side of the pond he noticed that his instrument was detecting a magnetic field that appeared to be in the air over the pond.

His first thought was that a "magnetic cloud" was over the pond. However, he subsequently realized that the source of the field seemed to be in the tops of some trees about sixty feet away on the other side. While looking over the four-to-five-foot-deep pond he noticed three depressed grass circles in the bottom. He had been fishing there several days earlier and had not seen any circles.      
       Several hours later the MUFON investigators arrived with a video camera and a Geiger counter. J. showed them the circles at the bottom of the pond and he also showed them the effect on his instrument of the strong magnetic field. (The Geiger counter detected no excess ionizing radiation.) Bruce Morrison's, videotape clearly shows the response of the gradiometer, which was operated in a completely normal way. (Tests carried out by J. at the time and later on at my request prove that the gradiometer was operating normally.) The gradiometer is designed so that it generates an audio tone, the pitch of which is very nearly proportional to the magnetic field gradient over a wide range of field strengths: the greater the field gradient, the higher the audio frequency. (Note: a gradiometer does not measure the actual value of the magnetic field at a point in space. A device such as a compass, a rotating coil of wire (with a voltmeter attached), a "Hall effect device" or a fluxgate magnetometer is needed to do that. Instead, the gradiometer measures the change in field strength with position and direction.) A nonmagnetized piece of magnetizable material such as an iron bar will distort the earth's field—just as a rock distorts the flow of a uniform stream of water—and the gradiometer can detect the distortion. A magnet or a loop of wire carrying a current is a source of magnetic field which varies with position relative to the source. The gradiometer detects the variation of the field around the source. In order to provide accurate gradient values the gradiometer was calibrated with a magnet of known strength by placing the magnet at varying distances from the end of the wand and recording the resulting frequencies. The results of the calibration and the calculations which provide the field-gradient strengths have been published in a paper entitled "Strong Magnetic Field Detected Following a Sighting of an Unidentified Flying Object" in the Journal of Scientific Exploration (See Reference 10).          
       Bruce first recorded J. standing on the north side of the pond looking southward toward the clump of pine trees and swinging the gradiometer back and forth. The gradiometer gave a clear indication of a strong field when it pointed in the direction of the trees which were about sixty feet away at the time. Furthermore, the maximum frequency, corresponding to about 0.18 Gauss per meter, was obtained when the gradiometer was tilted upward by an angle in the range 20°-30°, suggesting that the source of the field was at the tops of the trees or above the treetops (!). As the gradiometer rod was turned away from the direction of the tree-tops the frequency decreased. To confirm that the source was at the tops of the trees they all walked to the clump of pines. There the videotape shows that the highest frequency, corresponding to about 0.25 Gauss per meter, was obtained when the gradiometer was pointed upward toward the treetops. A search of the area failed to turn up any source of field other than the source which seemed to be at, or above, the treetops. While near the trees and pointed upward the audio pitch of the gradiometer was not steady, as it would be in the field of a magnet, but rather it pulsated, suggesting that the field itself was oscillating at a low frequency (about 10 Hz). The field gradient was so strong that it was roughly equivalent to the distortion in the earth's field caused by the presence of a destroyer battleship at a distance of eighteen meters! (Alternately, the field could have been created by a one-meter-diameter coil of wire at a distance of eighteen meters and with an ampere-turns product of about three million.)    
       J. reported that the next day during another search the magnetic field gradient had diminished greatly. On September 14 the MUFON investigators returned to the area and videotaped J. with his gradiometer standing under the same trees where there had been a huge magnetic field. This time there was no measurable field gradient. On that day the grass circles in the pond were measured and found to be about eleven feet in diameter. A week or so later the investigators thought of checking the magnetic field in the area with compasses at several locations. All the compasses pointed north, indicating that there was no large magnetic anomaly in the area. (It is unfortunate that they didn't think to use compasses on the day after the sighting!)           
       To understand the significance of the strength of the magnetic field gradient consider the following facts: wood is not ferromagnetic (it cannot be magnetized as iron can); while J. was standing under the trees with his gradiometer pointed upward and generating a high pitch on September 12, Bruce Morrison was videotaping the tops of the trees, which were silhouetted against a clear blue sky—they could see nothing up there that could cause such a field gradient; if, somehow, the wood had been made ferromagnetic by a UFO (an impossibility, according to the physics of magnetic materials), or if the UFO had deposited a massive amount of some ferrous (i.e., containing iron) magnetic material on the trees, then the strength of the magnetic field should have been the same on the second day of the investigation because ferrous materials do not lose their magnetism at environmental temperatures (they do lose it at temperatures of many hundreds of degrees); there had been rain off and on during the days following the sighting, yet there was no magnetic field near the ground, so no magnetic residue had washed off the trees. Hence we are left with a double mystery: how did the field get there in the first place, and, once there, why did it disappear?
