SNEWS is a network of neutrino detectors capable of monitoring for a burst of low energy neutrinos emitted from supernovae. SNEWS is unique in its physics goal: to alert the community to an imminent galactic supernova.
Users of SNEWS include neutrino experiments, astronomers, as well as the public include an active contingent of amateur astronomers. The existing SNEWS system sends alerts via an email list.
SNEWS alerts will be integrated into the larger alert framework being designed through the ACME project. The work performed under this project will allow better coordination between the different energy regimes that can be produced in supernovae, with SNEWS monitoring the low energy neutrinos and neutrino telescopes like IceCube and KM3NeT also monitoring at the highest energies.
