Supernova 1998bu in NGC 3368
Abstract
B. E. Schaefer, Yale University, reports the following magnitudes obtained with the 3.5-m WIYN telescope and based on ten Landolt comparison stars: May 23.18 UT, B = 12.34 +/- 0.04, V = 11.92 +/- 0.03; 26.14, 12.44 +/- 0.04, 11.94 +/- 0.03. Schaefer remarks: "Using these and other reported magnitudes (IAUC 6899, 6902, 6905, 6921), standard-template fits to the light curves of type-Ia supernovae (Schaefer 1996, Ap.J. 460, L19) suggest that peak magnitudes occurred on May 21.0 +/- 0.3, with B = 12.36 +/- 0.05, V = 11.93 +/- 0.04, and a decline rate in B from peak to 15 days later of 0.95 +/- 0.05."
