Hello Marcia,
The Super-Kamiokande neutrino detector has know a major disaster (all the light bulbs imploded in a chain reaction), but I don't think amateurs will go hunting for neutrinos. Rather for sudden flare somewhere. And with enough amateurs around the world, all linked to the internet through wireless means (in several years from now), it could become interesting. There are already campaigns to spot stellar occultations by asteroids (thereby estimating the asteroid shape) or with antennas, recording short waves radio emissions that determine meteorites entering the atmosphere.
