Abstract
Several independent reports have been received of the discovery of a supernova some 14" east and 12" south of the nucleus of NGC 5194 = = M51: Apr. 2.17 UT, mag 13.5 (Tim Puckett and Jerry Armstrong, Atlanta, GA; CCD discovery; R.A. = 13 27 47.62, Decl. = +47 26 59.1, equinox 1950.0); 2.19, 13.7 (Wayne Johnson and Doug Millar, Anza, CA; visual discovery with CCD confirmation); 2.21, - (Richard Berry, Cedar Grove, WI; CCD discovery); 2.66, 13.8 (Reiki Kushida, Yatsugatake South Base Observatory; visual). M. W. Richmond and A. V. Filippenko have confirmed the object using BVRI CCD images obtained with the 0.5-m Berkeley Automatic Imaging Telescope at Leuschner Observatory and note it to be very blue. L. Armus and J. M. Mazzarella obtained moderate-dispersion spectra with the 5-m Hale reflector at Palomar Observatory and see broad undulations superposed on a generally featureless continuum.
