Supernova 2011ar in UGC 2509 = PSN J03032521+0429399.
SILVERMAN J.M., CENKO S.B. and FILIPPENKO A.V.
Abstract (from CDS):
J. M. Silverman, S. B. Cenko, and A. V. Filippenko, University of California, Berkeley, report that inspection of a relatively noisy CCD spectrum (range 330-1000 nm), obtained on Mar. 9 UT with the 10-m Keck I telescope (+ LRIS), shows that PSN J03032521+0429399 = 2011ar is a type-II supernova. After removal of the host-galaxy recession velocity of 5860 km/s (measured from narrow host-galaxy emission lines), they find the absorption minimum of the H-alpha line to be blueshifted by about 7150 km/s.
