However, intermediate-width emission lines at wavelengths consistent with H-alpha and H-beta a redshift of z~0.26 are visible in each spectrum, along with weak narrow absorption from Mg II at z=0.259. Based on the presence of hydrogen we classify this as a SLSN-II, but given the weakness of this feature it may be more closely related to SLSNe-I. Further observations are planned to secure the subclassification and redshift. This event is currently at or just after peak (apparent mag r=17.8, or absolute mag M_g ~ -22.5), following a rise time of at least 50 days. 2020TNSCR.704....1P
