ASAS-SN

We obtained an optical low-resolution spectrum of supernovae candidates on UT 2018 July 14 with WFCCD mounted on the du Pont 2.5m telescope at Las Campanas Observatory. The spectrum of ASASSN-18mc/AT2018cjd is that of a Type Ia-norm supernova after maximum light. SNID (Blondin & Tonry 2007) gives a best fit age of +21.5 days after maximum light and z=0.027 as the redshift, consistent with the host galaxy redshift.
