Spectroscopy of PSN J00513484+2943149 in UGC 525
Abstract
We report that inspection of a low-dispersion optical spectrum (range 370-680 nm) of PSN J00513484+2943149 (CBAT TOCP), obtained in heavy twilight with the 2.3-m Bok telescope (+ Boller & Chivens spectrograph) at Steward Observatory on June 28 UT, shows it to be an aging type-Ia supernova. After correcting for a redshift of 4931 km/s for the assumed host galaxy, UGC 525 (Falco et al. 1999, PASP, 111, 438; via NED), reasonable matches are found with normal SNe Ia at epochs ranging between 40 and 65 days after maximum light, although there is a notable absence of emission in PSN J00513484+2943149 near 5000 Angstrom (attributed to Fe II; Branch et al.
