Supernova neutrino bursts have been observed from extra galactic distances.
This poster 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 brightness and time structure of the
SN1987A neutrino observations. We compare all 4 four reported
observations. Lensing could have distorted the time structure and the
observed luminosity of this burst.
