We report spectroscopic observations of ASASSN-18hq/2018arx (ATel #11541) and SN 2018ass obtained on UT2018-04-19.3 using the du Pont 2.5-m telescope (+ WFCCD) at Las Campanas Observatory. Targets were discovered by the All-Sky Automated Survey for Supernovae (ASAS-SN, Shappee et al. 2014) and Gaia Alerts (http://gsaweb.ast.cam.ac.uk/alerts/alertsindex). We used SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) to identify the type, phase, and redshift of the SN spectra.
SN 2018ass spectrum resembles Type IIP SN in its photospheric phase, and the spectrum of ASASSN-18hq matches with several SNe Type IIb near maximum. The SNID estimated redshifts of these SNe are consistent to those of their respective host galaxies.
