Porco Space Science Institute and the Cassini Imaging Science Team have reported the discovery, on IAUC 8389, of two new satellites of Saturn as designated above. S/2004 S1 has a revolution period of 1.01 days, semimajor axis 194,000km and estimated diameter of 3km. S/2004 S2 has corresponding values of: 1.14 days, 211000km, 4km. Visual magnitudes as seen from earth are in the range 22-23. SUPERNOVA 2004df IN ANONYMOUS GALAXY A report by A. V. Filippenko et. al. indicates a spectrum of this object found by Tom Boles (cf E-Circular 2018) of Aug 16 indicates it is of type II about 2 months after maximum. SUPERNOVA 2004di IN UGC 10097 A report by Filippenko of this object found by Mark Armstrong (cf E-Circular 2019) indicates from a spectrum of Aug 16 that it is of type Ia about three weeks past maximum.
