The radio emission light curve of the remnant of SN1987A is described with an application of the Sedov similarity solutions to established synchrotron emission theory. This model assumes that an electron acceleration mechanism exists which converts a fraction(f .002) of the total kinetic energy density into an energy density of relativistic electrons. It is also assumed that the relativistic electron ensemble and the magnetic field within the shock are in a state of energy density equipartition. This model is found to accurately describe the current radio light curve data. The developed theory is then utilized, in conjunction with 2-d hydrodynamic simulations performed by McCray and Luo (1993), to estimate the synchrotron emissions that are expected to occur starting around 1998 when the shock wave encounters the observed dense ring located .67 ly from the explosion center. Gamma Ray emissions from this event are also estimated using standard Bremsstrahlung theory. These emissions are predicted to be non-detectable thoughout the course of the shock's interaction with the ring.
