2001PASP..113.1349H BVRI Photometry of Supernovae WYNN C. G. HO, SCHUYLER D. VAN DYK, CHIEN Y. PENG, ALEXEI V. FILIPPENKO, DOUGLAS C. LEONARD, THOMAS MATHESON, AND RICHARD R. TREFFERS Department of Astronomy, 601 Campbell Hall, University of California, Berkeley, CA 94720-3411 AND MICHAEL W. RICHMOND Department of Physics, Rochester Institute of Technology, Rochester, NY 14623-5603 Received 1997 July 10; accepted 2001 August 13 ABSTRACT. We present optical photometry of one Type IIn supernova (1994Y) and nine Type Ia supernovae (1993Y, 1993Z, 1993ae, 1994B, 1994C, 1994M, 1994Q, 1994ae, and 1995D). SN 1993Y and SN 1993Z appear to be normal SN Ia events with similar rates of decline, but we do not have data near maximum brightness. The colors of SN 1994C suggest that it suffers from significant reddening or is intrinsically red. The light curves of SN 1994Y are complicated; they show a slow rise and gradual decline near maximum brightness in VRI and numerous changes in the decline rates at later times. SN 1994Y also demonstrates color evolution similar to that of the SN IIn 1988Z, but it is slightly more luminous and declines more rapidly than SN 1988Z. The behavior of SN 1994Y indicates a small ejecta mass and a gradual strengthening of the H{alpha} emission relative to the continuum.
