... when she observed a phenomenon that seems to have been an elaborate and hard-to-explain form of ball lightning. When the BL appeared suddenly from behind the tree, it caught the attention of the witness who said that it looked like it "sat down on to the tree." It had the dimensions of "a small truck tyre, not as large as a tractor one," and it had a definite torus shape. What made the dark object an even stranger sight was a considerable number of "Xmas candies", all hanging down from its underside 15 to 20 centimetres long and "sparkling", which means changing brightness with an emission of sparks at the same time. A humming and sizzling sound was associated with the optical effect, but there was no static electricity. The strange light was not blinding, but irritated the eyes of the witness who looked at it only intermittently. Mrs. Reisinger continued her work in the shed, not moving closer to the object and getting more nervous over the 10 minutes that the phenomenon lasted. Her eyes started to water towards the end of the observation. Another phenomenon that she remembers was the irregular extinction of the "candies" which went out piece by piece. (Keul, Alexander G.; "More on a Torus Ball-Lightning Case," Journal of Meterology, U.K ., 25:49, 2000. The initial report was presented in the same journal, 24:178, 1999.) Comment. The buzzing sound remarked upon above leads us to the even weirder phenomenon ...

... that have transpired, Galileo has radioed back voluminous data about Jupiter itself and its four large Calilean satellites. These natural satellites have turned out to be a disparate bunch. Three have iron cores, but Callisto breaks the mold with an unusual core of mixed ice and rock. Europa probably possesses an ocean, and Callisto might also. Only one of Jupiter's large satellites, Ganymede, boasts a magnetic field. In fact, Ganymede is apparently the only satellite in the solar system to display an intrinsic, dipole magnetic field like the earth's . Although Ganymere's magnetic field is like that produced by a permanent bar magnet, its core is much too hot for permanent magnetism. Again like the earth, Ganymede's field is theorized to be generated by the convection of electrically conducting liquid in its core -- a dynamo of sorts. All well and good, but Ganymede is so small that it should have cooled off billions of years ago thereby freezing its metallic core. So then, whence its magnetic field? One way out of this box it to suppose that about a billion years ago Ganymede was circling Jupiter in an orbit that took it much closer to this ponderous planet. Then, Jupiter's powerful gravitational field would have gently kneaded Ganymede's structure creating what is called "tidal heating," which kept the core liquid and able to generate a magnetic field. (Johnson, Torrence V.; "The Galileo Mission to Jupiter and Its Moons," Scientific American, 282:40, February 2000.) Comment. Sounds good ...
