We obtained an optical spectrum (range 350-820 nm) of CSS150119:125801+035333 on UT 2015 Jan.20.88 with the 2.4-m telescope (+YFOSC) at LiJiang Gaomeigu Station of Yunnan Observatories. The spectrum is similar to that of a type IIn supernova two months after the maximum light. Cross-correlation with a library of supernova spectra using the comparison tool SNID (Blondin and Tonry 2007, ApJ, 666, 1024) shows that it matches with SN 1996L at t = +58 days. From the narrow hydrogen emission lines, we estimate that the host galaxy of this supernova has a redshift of 0.105.
