We present UBVRI photometry of the supernova 1993J taken by the Berkeley Automated Imaging Telescope (BAIT) at Leuschner Observatory. BAIT is a robotic telescope system capable of automatically taking CCD images. Data were taken on both the 20'' and 30'' telescopes. Preliminary analysis of the data confirms the reddening observed during the decline from maximum brightness. The prospective plateau phase will be covered extensively by our data and will permit us to calculate the integrated optical fluxes and color temperatures.

This is work in progress and the data we present will cover the light curve covering the first two months of SN1993J.
