Prospects for correlated observations of galactic supernovae and young remnants

The observations needed to detect and characterize potential Galactic supernova outbursts or their young remnants are discussed. The occurrence rate of a Galactic outburst is estimated as 0.01-0.1/yr, and the need for an organized program of observations is stressed. Types of radiation to be observed include 10-20-MeV neutrinos, gravitational waves, near-IR light (valuable as an early source which can be located precisely), radio emission (for type-II supernovas), gamma rays of energy 100 MeV or more, neutrinos of energy 100 GeV or more, and neutrons of energy 1 EeV or more. Consideration is also given to the availability of facilities capable of monitoring these emissions.
