Shappee (IfA, UH Manoa), Subo Dong, Subhash Bose (KIAA, PKU)SCATSN Ia0.0391SCATThe Spectral Classification of Astronomical Transients (SCAT) survey reports the classification of ASASSN-18kn (SN2018btm) as a Type Ia supernova roughly a month after maximum light. The observations were taken with the SuperNova Integral Field Spectrograph (SNIFS) on the University of Hawaii 88-inch (UH88) telescope ranging from 330-970nm. The classification was determined using a library of supernovae spectra (SNID, Blondin & Tonry 2007, ApJ, 666, 1024). The spectrum also matches that of a 91bg-type SN Ia but the quality is too poor to say definitively. 2018TNSCR.814....1T

At the redshift of 0.0435, the absolute magnitude at the discovery was ~ -19 mag which is consistent with the Ia classification and its phase.2018TNSCR.962....1H

The spectrum of ASASSN-18om/AT2018ddx is that of a Type II supernova before maximum light, showing a blue continuum and broad/weak H-alpha in emission. SNID gives a best fit subtype SN IIb with an age of -7.4 days before maximum light and z=0.027 as the redshift.

We identify some features as likely being He II 4686, H beta, He I 5876, and H alpha in emission. All lines have FWHM of ~12,000 km/s. Using a distance modulus of 34.4 mag to the host galaxy and correcting for MW extinction, the discovery magnitude corresponds to M = -18.5 mag, similar to other TDEs, but more luminous than most SNe II. From the confirmation image, the transient appears coincident with the nucleus of its host galaxy. ATel 118652018TNSCR.998....1P
