Shappee (IfA, UH Manoa), Subo Dong, Subhash Bose (KIAA, PKU)SCATSN Ia0.034SCATAs part of the Spectral Classification of Astronomical Transients (SCAT) survey, we obtained a spectrum (330-970nm) of SN2018btb (expt 1200s) on MJD 58281.31 using the SuperNova Integral Field Spectrograph (SNIFS) on the University of Hawaii 88-inch (UH88) telescope. Cross-correlation with a library of supernovae spectra (SNID, Blondin & Tonry, 2007, ApJ, 666, 1024B) returned a good match with several normal Type Ia supernovae roughly 2 weeks past maximum light.
