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.

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

The SN seems to be peculiar, because ASAS-SN reported V = 16.50 mag on 2018-07-21 and g=17.3 mag on 2018-07-22, suggesting an intrinsic red colour or a fast decline in the SN brightness. The classification spectrum does not look peculiarly red, suggesting a fast photometric evolution rather than red colours. We encourage photometric follow-up.2018TNSCR1049....1C
