M. Nakahata, Kamioka Observatory, Institute for Cosmic Ray Research,
University of Tokyo, reports on behalf of the Super-Kamiokande collaboration:

Super-Kamiokande, a 50 ktons water Cherenkov imaging detector situated 1000 meters underground in the Kamioka mine, Gifu, Japan, has searched for neutrino signal correlated with SN2023ixf in a time window 2 days before the detection by Oak St. Observatory (2023-05-17 08:45:13 to 2023-05-19 08:45:13), during which Super-Kamiokande took data stably without dead time. In the electron total energy region between 7.0 MeV and 100 MeV within a fiducial volume of 22.5 ktons, no significant signal was observed.
