The Nordic Optical Telescope (NOT) Unbiased Transient Survey (NUTS; ATel #8992) reports the spectroscopic
classification of ZTF19aadnxat/SN 2019vu, SN 2019yc and ZTF19aaedpuk/SN 2019yv in host galaxies MCG +10-20-065, NGC 0201 and NGC 3818, respectively.
The candidates were discovered by the Zwicky Transient Facility and Koichi Itagaki.
The observation(s) was(were) 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
ZTF19aadnxat | SN2019vu | 2019-01-11 | 17.5 | 2019-01-25 | 0.033 | Ia | +0d | -
AT2019yc | SN2019yc | 2019-01-22 | 16.7 | 2019-01-25 | 0.006 | II | young |(1)
ZTF19aaedpuk | SN2019yv | 2019-01-23 | 16.7 | 2019-01-25. | 0.015 | - | - |(2)
(1) Young Type II (likely IIb), blue continuum with weak Halpha emission
(2) We see a red spectrum consistent with host galaxy light, and without any obvious SN or TDE features
Classifications were performed using the SNID (Blondin and Tonry 2007, ApJ, 666, 1024) tool. Calibrated spectra and additional information can be retrieved in the IAU Transient Name Server.
