        BV PHOTOMETRY OF SUPERNOVA IN NGC 1316



   BV photometry of the supernova (Maza, 1980) in Fornax A (NGC 1316),
the first of two supernovae discovered in that galaxy, is reported.
Observations were obtained with the CTIO 0.6 m telescope (S-20 phototube)
and 0.9 m telescope (GaAs phototube). Extinction and transformation
coefficients for each night were determined by observing equatorial
standards (Landolt, 1973). Typically, at least 15 standards were observed,
and several were observed at a variety of air masses. The standard
deviation of a single measurement is typically 0.015m in B-V and 0.03m in V.
