The NOT Unbiased Transient Survey (NUTS; ATel #8992) collaboration reports the spectroscopic classification of supernovae SN 2018aei and SN 2018aej, discovered by PanSTARSS Survey for Transients (ATel #11408). Both SNe are in the same host galaxy 2MFGC 12659.
The observations were performed with the 2.56 m Nordic Optical Telescope equipped with ALFOSC (range 350-950 nm; resolution 1.6 nm) on 2018-03-24.1 UT.
Survey Name | IAU Name | Discovery (UT) | Discovery mag | Observation (UT) | Redshift | Type | Phase | Notes
PS18mi | SN 2018aei | 2018-03-08.5 | 19.13 | 2018-03-24.1 | 0.048 | II | 2wk post-max | (1)
PS18mh | SN 2018aej | 2018-03-08.5 | 18.42 | 2018-03-24.1 | 0.048 | Ia | 1wk post-max | (1)
(1) Redshift was derived from the SN and host absorption features, consistent with that from SDSS spectrum of the galaxy.
Classifications were performed using the GELATO (Harutyunyan et al. 2008, A&A, 488, 383) and SNID (Blondin and Tonry 2007, ApJ, 666, 1024) tools. Calibrated spectra and additional information can be retrieved in the IAU Transient Name Server.
