(1) Best match with several normal Type-Ia SNe, around 1 week before B-band maximum light. The expansion velocity, as deduced from the position of the minimum of the Si II 635 nm line, is about 13600 km/s. The redshift adopted for UGC 2561 is from Huchra et al. 1999, ApJS 121, 287.
Classification were done with GELATO (Harutyunyan et al. 2008, A&A, 488, 383) and SNID (Blondin and Tonry 2007, ApJ, 666, 1024). The Asiago classification spectra are posted at the website http://sngroup.oapd.inaf.it.
