SuperNova Early Warning System (SNEWS)
Start: 2004
Data Archives: GCN Classic
SNEWS is a consortium of MeV neutrino facilities which work together to distribute early warning alerts for core-collapse supernovae, reporting the neutrinos released during the collapse event before the first light of the supernova escapes.
