We report the spectroscopic classification of SN 2019klk (ATLAS19olk, ZTF19abddsvk)
as a type IIP supernova in the galaxy SDSS J121438.89+652654
(z = 0.0583508 +/- 0.0000175) from observations with SPRAT (Piascik et al. 2014)
on the 2-m Liverpool Telescope (LT; Steele et al. 2004) made on 2019 July 19 22:40:10 UT and
OSIRIS
on the Gran Telescopio Canarias (GTC)
made on 2019 July 21 21:56:47 UT. The TNS classification of Prentice et al. , based on Liverpool Telescope SPRAT observations made on 2019 July 14 21:49:07 UT, reports "Probable SN II given the bump around H alpha, The H alpha may be from the transient or it may be from the host, our low S/N spectrum is far from conclusive."
Our LT and GTC spectra show broad H alpha emission. Comparison of the GTC spectrum with several libraries of SNe spectra with SNID (S. Blondin & J. L. Tonry 2007, ApJ, 666, 1024) shows that SN 2019klk is likely a type IIP SN (similar to SN 2004et) at z = 0.058 +/- 0.004, about 6 to 10 days after maximum. The peak absolute luminosity (M (r) = -18.3) is large compared with other type IIP SNe.
Based on observations made with the Liverpool Telescope and the Gran Telescopio Canarias (GTC), installed at the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofisica de Canarias, in the island of La Palma. We thank the LT and GTC staff for their continuous support.
