Bruch, A. Gal-Yam (Weizmann)adH0ccSN Ib0.036adH0ccThe adH0cc programme for an "accurate determination of H0 with core-collapse supernovae" reports the classification of the optical transient SN 2019wxt. The target was supplied by the Pan-STARRS Survey for Transients (Chambers et al. 2016 2016arXiv161205560C), through McLaughlin et al. AstroNote 2019-154 and McBrien et al., GCN 26485. We selected this target as a possible young SN II, at the right magnitude in our target redshift range for SNe II-P in the Hubble flow. The observations were performed on the night of 2019 December 18 with the ESO Very Large Telescope UT1, equipped with the FORS2 spectrograph and grism 300V, covering a wavelength range from 3400 to 9600A at a resolution of 10A. The spectrum is dominated by a blue continuum (see also Dutta et al., GCN 26490; Izzo et al., GCN 26491; Srivastav & Smartt, GCN 26493; Müller Bravo et al., GCN 26294 and AstroNote 2019-156), with a few broad undulations and with narrow H II-region lines superimposed. From the narrow emission lines, we derive a redshift of z = 0.036, in agreement with the spectroscopic redshift of the host galaxy. Some of the weak, broad features can be attributed to helium lines, with the 5876A and 7065A lines of He I providing the cleanest identifications. Broad hydrogen lines are not unambiguously detected. Based on these properties, we classify SN 2019wxt as a young SN Ib, but note similarities to some SNe IIb such as SN 2011fu (Morales-Garoffolo et al. 2015, MNRAS, 454, 95) at comparably early phases.2019TNSCR2900....1V
