International audience The KM3NeT collaboration has started the construction of the ARCA and ORCA neutrino telescopes in the Mediterranean Sea. With the most recent data from the deployed lines, the detection technique for Core-Collapse Supernova neutrino bursts has been refined. The real time trigger was implemented and verified to be robust and effective. %The first results are presented here.The study of the resolution to fast-time variation in the neutrino light-curve is also presented exploiting two different methods, with estimates from real data and state-of-the-art Core-Collapse Supernova simulations.Finally, the mean energy of the incoming neutrinos can be estimated through the correlation between the number of photo-multipliers detecting light in coincidence and the mean energy of the incoming neutrinos.
