We report UBVRI photometry of SN 1993J in M 81 during the first 450 days after its initial brightening. Wide field CCD images of the supernova and surrounding comparison stars were obtained with the CWRU's Burrell Schmidt Telescope at KPNO. Nearly continuous photometric coverage was obtained during the first three months of the outburst, with roughly bi-monthly coverage during the subsequent year. We present the UBVRI and color light curves and discuss the evolutionary stages of the outburst. NMS and TJB acknowledge support of the AAS-REU program and the NY State Pew Science Cluster.
