The next galactic core-collapse supernova will deliver a wealth of neutrinoswhich for the first time we are well-situated to measure. These explosionsproduce neutrinos with energies between 10 and 100 MeV over a period of tens ofseconds. Galactic supernovae are relatively rare events, occurring with afrequency of just a few per century. It is therefore essential that allneutrino detectors capable of detecting these neutrinos are ready to trigger onthis signal when it occurs. This poster describes a data-driven trigger whichis designed to detect the neutrino signal from a galactic core-collapsesupernova with the NOvA detectors. The trigger analyzes 5ms blocks of detectoractivity and applies background rejection algorithms to detect the signal timestructure over the background. This background reduction is an essential partof the process, as the NOvA detectors are designed to detect neutrinos fromFermilab's NuMI beam which have an average energy of 2GeV--well above theaverage energy of supernova neutrinos.
