The Nordic Optical Telescope (NOT) Unbiased Transient Survey (NUTS; ATel #8992) reports the spectroscopic
classification of ATLAS17lbl (SN 2017gup) in an anonymous host galaxy. The candidate was discovered by the ATLAS survey, see Tonry et al. (2011, PASP, 123, 58) and Tonry et al. (ATel #8680).
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
ATLAS17lbl | SN 2017gup | 2017-09-17.56 | 17.8 | 2017-10-01.05 | 0.016 | Ia | +4d | (1)
(1) The best match using SNID is type Ia supernova SN 2007fs at phase ~+4 days, and the best-fit SN redshift is 0.016.
Classification was performed using SNID (Blondin and Tonry 2007, ApJ, 666, 1024) tools. Calibrated spectra and additional information can be retrieved in the IAU Transient Name Server.
