2011CBET.2634....2L

L. Lopez, D. Kirkman, and D. Tytler, University of California, San Diego, obtained a spectrum (range 310-810 nm) of 2011H with the 3-m Shane reflector (+ Kast) at Lick Observatory on Jan. 9 UT. Cross-correlation with a library of supernova spectra using the "SuperNova IDentification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) indicates that 2011H is a normal type-Ia supernova somewhat past maximum light. A redshift of z = 0.020 ± 0.003 is derived, based on the broad supernova features, consistent with the reported redshift for UGC 1837 (z = 0.021955 from NED). However, due to the large spatial offset, the supernova's host-galaxy identification is quite ambiguous. Given that UGC 1837 resides in a galaxy group, 2011H could be an intracluster supernova, or the progenitor system may have originated in a more nearby, faint, and uncatalogued group member.
