Gravitational Lensing of Supernova Neutrino Bursts

Supernova neutrino bursts have been observed from extragalactic distances.  This note addresses the question of how gravitational lensing could distort the information in the burst.  We apply the gravitational lens hypothesis to try to understand the time and brightness structure of the SN1987A neutrino observations.  The Kamiokande and Baksan neutrino observations of SN1987A have the time and brightness distribution expected from a lensed event.  Estimates of a possible lensing mass and alignment are made.  These estimates suggest a path to verification.
