In this work I investigate the possibility of Type II supernovae being the origin for positrons producing observed annihilation radiation observed toward the Galactic center. It was my contention that the decay of $\sp{56}$Co coupled with falling densities would allow for the production and extended existence of positrons in the supernova outflow. Supernova 1987A has prompted many people to construct models of supernova outflow. I use the results of two existing models as the initial conditions in my models. I have created both an analytic and a computer model for the survival of positrons. These models show that while Type II supernovae fall short of the needed production of surviving positrons, the lower densities existing in Type I supernovae may be a more promising source.
