  Observation of supernovae (SN) through their neutrino emission is a
fundamental point to understand both SN dynamics and neutrino physical
properties. JUNO is a 20kton liquid scintillator detector, under construction
in Jiangmen, China. The main aim of the experiment is to determine neutrino
mass hierarchy by precisely measuring the energy spectrum of reactor electron
antineutrinos. However due to its properties, JUNO has the capability of
detecting a high statistics of SN events too. Existing data from SN neutrino
consists only of 24 events coming from the SN 1987A,the detection of a SN burst
in JUNO at $\sim 10 kpc$ will yield $\sim 5 x 10^{3}$ inverse beta decay (IBD)
events from electron antineutrinos, about 1500 from proton elastic scattering
(pES) above the threshold of 0.2 MeV, about 400 from electron elastic
scattering (eES), plus several hundreds on other CC and NC interaction channels
from all neutrino species.
