3512016-08-27 08:23:31linatomaLina TomasellaPadova-AsiagoSN II0.032Padova-AsiagoAlready observed on 2016-08-23.08: the previous spectrum showed a blue, featureless continuum (Atel #9397). This new spectrum clearly shows a broad Halpha and we can classify it as a Type II SN soon after explosion, with the best match being with SN 1999gi (Smartt et al. 2001, ApJ 556L, 25S) at phase around 1 week. From the position of the minimum of the Halpha feature, we infer an expansion velocity of 13500km/s for the ejected material. The redshift has been measured from a narrow emission superimposed to the broad Halpha.2016TNSCR.597....1T
