Solar Flare neutrinos and flavors detections, related to neutron late burst

Largest Gigaton array detectors as ICECUBE as well as the lower energy Megaton ones, as Deep Core and HyperKamiokande, might in a near future reveal neutrino signals correlated to hard X-gamma solar flares. Their detection might also be correlated to fast later neutron burst. These multi-messanger astronomy might offer a new tool to test neutrino mixing as well as the first discover of a solar muon neutrino astronomy.
