Abstract
Superconductive technologies developed over the last decade now allow detailed observation of flux quantization in five centimeter diameter rings. The theoretical similarities between flux quantization and Dirac magnetic charges make superconductive systems natural detectors for these elusive particles. Recent work on Grand Unification theories, the topic of this workshop, strongly suggests the existence of stable supermassive magnetically charged particles. These particles would be nonrelativistic, weakly ionizing, and very penetrating; and thus may have eluded previous searches. A new superconductive detector designed to look for an extraterrestrial flux of such particles has been operating for more than six months and the first results include a single event. It is consistent in magnitude with the passage of a particle possessing a single Dirac unit of magnetic charge.
