We have made a new determination of the supernova rate based on more supernova discoveries, better light curves, and an improved estimate of the detection threshold of our search. This threshold depends not only on the seeing and atmospheric extinction, but also on a recently discovered time dependant telescope/optics transmission. We also derived the bandpass of the detector/telescope system from observations of M67 and Landolt standards taken near the end of the nearby search; this determines the color of the light curves from which surveillance times are calculated. In the end we calculate surveillance times for both visual and red light curves and absolute magnitudes, as the bandpass was a time dependant combination of both.
