Dong (KIAA-PKU) ASAS-SNSN II0.0131ASAS-SNWe obtained an optical low-resolution spectrum of supernovae candidates on UT 2018 July 13-14 with WFCCD mounted on the du Pont 2.5m telescope at Las Campanas Observatory. The type determination and the age or redshift given, are implemented from SNID (Blondin & Tonry 2007). The spectrum of ASASSN-18nu/AT2018cue is that of a Type IIP supernova after maximum light. SNID gives a best fit age of +18 days after maximum light and z=0.013 as the redshift.

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.

Andrew Howell, Curtis McCully, Stefano Valenti Global SN ProjectSN Ia0.0411Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find good fits to several Type Ia supernovae around the maximum light at the redshift of 0.041. At the redshift of 0.041, corresponding to the distance modulus of 36.26, the absolute magnitude in V-band taken at 2018-10-08 23:48:10 is -19.04 mag which is consistent with the Ia classification and its phase. We measure the SiII velocity of 11,000 km/s from the absorption lines.
