We have obtained an optical spectrum of SN 2019uxh, which reveals it to be a young Type II supernova.

The adH0cc programme for an "accurate determination of H0 with core-collapse supernovae" reports the classification of the optical transient SN 2019uxh. The target was supplied by the Pan-STARRS Survey for Transients (Chambers et al. 2016 2016arXiv161205560C) and the ATLAS survey (Tonry et al. 2018, 2018PASP..130f4505T). The observations were performed on the night of 2019 November 20 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.

From the spectroscopic appearance and the photometric constraints, we estimate a phase about 2 weeks after explosion. Weak Na D absorption in the supernova rest frame suggests some extinction within the host galaxy.22:51:04.988-11:47:14.95SN II0.0326
