Super-Kamiokande-I studied low energy neutrino interactions above 4.5 MeV. Photo-cathode coverage has been restored to 40% in Super-Kamiokande-III in order to observe Cherenkov events with an energy even below 4.5 MeV. This is motivated by the transition of solar neutrino oscillations between vacuum and matter-dominated oscillations near 3 MeV and delayed neutron detection from inverse-beta interactions. I will discuss the progress in event reconstruction and background suppression as well as future measurements which a lower analysis and hardware energy threshold will make possible.
