On behalf of a Danish Summer School in Observational Astrophysics currently being held at the Nordic Optical Telescope,
we report the spectroscopic classification of ASASSN-18rt (IAU name SN 2018fav).
The candidate was discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN: Shappee et al. 2014) on 2018-08-12.9 with an apparent g-band magnitude of 18. The host galaxy is 2MASX J00455851-2156353 and has a redshift of z=0.037923 (Jones et al. 2009).
Observations were performed with the 2.56 m Nordic Optical Telescope equipped with ALFOSC (range 350-950 nm; resolution 1.6 nm FWHM) on 2018-08-16.2. Close inspection of the spectrum reveals it to most likely be a Type-Ic around maximum light. Comparison of the spectrum with a library of template spectra using SNID (Blondin and Tonry 2007) reveals decent matches with SN 2004aw around maximum light.
