The Nordic Optical Telescope (NOT) Unbiased Transient Survey (NUTS; ATel #8992) reports the spectroscopic
classification of ASASSN-18bq in an unknown host galaxy.
The candidate was discovered by the All-Sky Automated Survey for Supernovae (ATEL #8944, #8979).
The observation was performed with the 2.56 m Nordic Optical Telescope
equipped with ALFOSC (range 350-950 nm; resolution 1.6 nm FWHM).
Survey Name | IAU Name | Discovery (UT) | Discovery mag | Observation (UT) | Redshift | Type | Phase | Notes
ASASSN-18bq | SN2018mc | 2018-01-29.51 | 17.4 | 2018-02-14.27 | 0.035 | IIb | Post-max| (1)
(1) Redshift z = 0.03-0.04 based on SN features. Matches type IIb SNe few days after maximum light.
Classification was 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.
