Title: Optical and infrared photometry of bright supernovae

Abstract: We request continuing queue-scheduled observations of bright supernovae with the 1.3-m telescope. Over the past 4 years we have accumulated optical and IR photometry of roughly 20 Type Ia and Type II supernovae. Some well-sampled light curves have already been published (e.g. SNe 1999aw, 1999ee, 2000cx, 2001el) while others are being written up (e.g. SNe 1999ac, 2000bh, 2000ca, 2001ba). We are in the process of characterizing the IR properties of supernovae. For Type Ia SNe this allows an accurate determination of the dust extinction along the line of sight. In order to know the intrinsic scatter of the light curves of SNe, we need to continue observing bright, nearby objects. Many key projects (e.g. ESSENCE) depend on a better understanding of the nearby objects. Every bright, nearby supernova has the potential for independent distance estimates, which is important for anchoring the cosmological distance scale.
