We obtained a spectrum of PS17ha / AT2017jc on 2017 January 16.8 UT with
the Nordic Optical Telescope, using ALFOSC, grism 4 (320-910 nm, 16 Angstrom resolution) and 1" slit.
The target was supplied by Pan-STARRS Survey for Transients
(see Chambers et al. 2016, arXiv:1612.05560), via the TNS.
Classification was done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
We find several good fits to a normal SN Ia around maximum light at a redshift of 0.07.
This redshift is consistent with the photometric redshift (0.08) of the nearby galaxy
SDSS J233710.60-021036.9, and we note that the galaxy is a KEGS source.
We acknowledge help from the KEGS and PESSTO teams.
