SN II

0.007

Global SN Project

The spectrum appears to be blue and almost featureless. A broad and shallow P-Cygni profile can be distinguished at around 6600 ang, and can be tentatively identified as Ha, although Hb cannot be clearly distinguished. Assuming the transient is associated with the nearby galaxy NGC 4192A, we adopt a redshift of 0.007. At this redshift, from the position of the minimum of Ha we measure an expansion velocity of ~13000 km/s. Therefore, we classify the object as a young type II SN. For reference, SNID (Blondin & Tonry 2007, ApJ, 666, 1024) finds some similarities with young IIb SNe.
