The 1959 Supernova, SN 64

Jesse L. Greenstein, F. Zwicky
1962 Publications of the Astronomical Society of the Pacific  
The galaxy in which the supernova appeared is an open barred spiral of integrated photographic apparent magnitude m pg =15.4 (see Plate I). With the indicative absolute distance of 29.90 million parsecs, as derived below, the indicative 3 photographic absolute magnitude of the galaxy thus is M^(galaxy) = -17.0 (1) The apparent dimensions of the galaxy in seconds of arc are d ± = 83'.'4 , d 2 = lO'.'O . The indicative absolute dimensions normal to the line of sight are therefore Z)i = 12,100
