[SH162] Observing future Solar Flare Neutrino in HyperKamikande and ICECUBE
The largest Solar flare have been recorded in gamma flash and hard spectra up to tens GeV energy. The present building and upgrade of HyperKamiokande, HK, and ICECUBE (as well as Deep Core, Pingu) neutrino detectors do offer a novel way to largest trace of solar Flare: their sudden anti-neutrino (or neutrino) flare made by proton scattering and pion decays via Delta resonance production. These signals might be observable at largest flare by HK via soft spectra up to tens-hundred MeV energy and by ICECUBE-PINGU at higher, GeV up to hundred GeV, energies. We show the expected rate of signals for the most powerful solar flare occurred in recend decades.
