Abstract (from CDS):
T. Matheson, P. Challis, and R. Kirshner, Harvard-Smithsonian Center for Astrophysics, report that a spectrum (range 370-750 nm) of SN 2003O (cf. IAUC 8055), obtained by M. Calkins on Jan. 25.12 UT with the Mt. Hopkins 1.5-m telescope (+ FAST), shows it to be a type-II supernova. Adopting the NASA/IPAC Extragalactic Database recession velocity of 4941 km/s for the host galaxy, the expansion velocity derived from the minimum of the H-beta line is 9100 km/s.
