[45.10] The Supernova Early Warning System (SNEWS)

A. Habig (Univ. of Minnesota Duluth), SNEWS Collaboration

SNEWS is a cooperative effort between the world's neutrino detection experiments to spread the news that a star in our galaxy has just experienced a core-collapse event and is about to become a Type-II Supernova. This project exploits the ~hours time difference between neutrinos promptly escaping the nascent supernova and photons which originate when the shock wave breaks through the stellar photosphere, to give the world a chance to get ready to observe such an exciting event at the earliest possible time. A coincidence trigger between experiments is used to eliminate potential local false alarms, allowing a rapid, automated alert. SNEWS is currently operational and ready, and this poster presents the procedures in use. SNEWS work is supported by NSF collaborative grant #0302166.
