Description
We know since SN1987A that supernova explosions produce a massive amount of neutrinos, this neutrinos burst arrive few minutes to several hours earlier than the electromagnetic signal from the supernova. Hence, detecting the neutrino burst can provide an early warning to telescopes, giving them an opportunity to look for the break-out light of the supernova. Large water cherenkov detectors are the main the main neutrino detector able to provide this warning. In Super-Kamiokande, we are continuously monitoring our data in order to detect any neutrino burst. In this presentation, we will present the recent upgrade of our alert system, with new methods to estimate the distance from the supernova, as well as the organization of a collaborative network of telescopes to ensure follow-up observation can process smoothly.
