  The Sudbury Neutrino Observatory (SNO) has unique capabilities as a supernova
detector. In the event of a galactic supernova there are opportunities, with
the data that SNO would collect, to constrain certain intrinsic neutrino
properties significantly, to test details of the various models of supernova
dynamics, and to provide prompt notification to the astronomical community
through the Supernova Early Warning System (SNEWS). This paper consists of a
discussion of these opportunities illustrated by some preliminary Monte Carlo
results.
