Spyromilio, B. Leibundgut (ESO)adH0ccSN II0.0476adH0ccThe spectrum shows a relatively featureless, blue continuum with broad He II emission superimposed, characteristic of a young Type II supernova. A weak, narrow He II emission line is also detected, suggesting long-lasting flash ionisation of a surrounding CSM. The appearance of the spectrum is consistent with the phase of 7d after explosion estimated from the ZTF and ATLAS light curves. At an absolute magnitude of -18.4 as inferred from our V-band acquisition image, the SN is very bright for a SN II.
