The Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose neutrino experiment primarily focused on determining the mass ordering of neutrinos using reactor antineutrinos. The JUNO detector is equipped with a 20-kiloton liquid scintillator target, monitored by 17,612 20-inch photomultiplier tubes (PMTs) and 25,600 3-inch PMTs.The construction of the JUNO detector was completed in 2024, followed by the water and liquid scintillator filling phase. The official data taking began in August 2025.
JUNO's unique detection capabilities for multi-flavor neutrinos from core-collapse supernovae position it as an outstanding observatory for supernova bursts and other transient events. In this talk, I will provide an overview of JUNO's redundant supernova monitoring system and report on its implementation and current operational status. The system consists of a Prompt Monitor at the CTU stage, an Online Monitor at the DAQ stage, and a Multi-Messenger Monitor based on low-threshold triggers. This setup ensures second-level alert generation while maintaining full coverage of the Milky Way. Additionally, I will discuss the physics potential of supernova neutrino detection and the implications of multi-messenger observations.
