62016-01-11 09:33:40xwangJujia Zhang (YNAO), Xiaofeng Wang(Tsinghua University)SN Ic-BL0.009The spectrum shows that SN 2016G is a broadlined type Ic supernova that is similar to SN 2007ru at t = +4.6 days from the explosion. We measure an expansion velocity of about 22000 km/s from Si II 635.5 nm absorption.
