\noindent We present a progress report on the Berkeley Automatic Imaging Telescope (BAIT) project, which uses the fully robotic 0.5-m and 0.76-m telescopes at the Leuschner Observatory near the UC Berkeley campus. One of the main scientific programs with the 0.76-m telescope is the Leuschner Observatory Supernova Search (LOSS), which monitors 677 northern galaxies for supernovae. This search began in winter 1992 and particularly emphasizes early detection. So far LOSS has discovered six supernovae (1992bt, 1993G, 1993R, 1993X, 1993Z, and 1994D). We present performance and supernova rate statistics derived from LOSS. Additionally, the 0.5-m telescope is used for long-term photometry of supernovae, active galactic nuclei, and other variable and ephemeral objects. We present and analyze the multi-band light curves for 15 recent supernovae obtained with both the 0.5-m and 0.76-m telescopes, including the bright supernovae SN 1993J, SN 1994D, SN 1994I, and SN 1994Y. A robotic 0.76-m telescope, the Katzman Automatic Imaging Telescope, will soon be installed at Lick Observatory to continue the scientific objectives and advance the performance of this project.
