THE TYPE Ia SUPERNOVA 1998bu IN M96 AND THE HUBBLE CONSTANT
We present optical and near-infrared photometry and spectroscopy of the type Ia SN 1998bu in the Leo I Group galaxy M96 (NGC 3368). The data set consists of 356 photometric measurements and 29 spectra of SN 1998bu between UT 1998 May 11 and July 15. The well-sampled light curve indicates the supernova reached maximum light in B on UT 1998 May 19.3 (JD 2450952.8±0.8) with B = 12.22 ± 0.0
