1284 2017-10-11 16:15:31 Jose Prieto S. Dong (KIAA), D. Bersier (LJMU), J. L. Prieto (UDP) ASAS-SN SN IIn 0.0173 1 ASAS-SN We obtained an optical spectrum of AT2017hcc on 2017 October 7.4 with FLOYDS mounted on the FTS 2m at the Siding Spring Observatory. The spectrum shows a relatively blue continuum with one strong, resolved emission line at 6676.3 Angstrom with FWHM~44 Angstrom (~2000 km/s). Assuming that this line is likely Halpha, then AT2017hcc is likely a Type IIn SN at z=0.0173. 2017TNSCR1103....1D
