We have simulated the response of a high energy neutrino telescope in
deep Antarctic ice to the stream of low energy neutrinos produced by a
supernova. The passage of a large flux of MeV-energy neutrinos during
a period of seconds will be detected as an excess of single counting
rates in all individual optical modules. We update here a previous est
imate of the performance of such an instrument taking into account the
recent discovery of absorption lengths of several hundred meters for
near-UV photons in natural deep ice. The existing AMANDA detector can,
even by the most conservative estimates, act as a galactic supernova
watch.
