We obtained an optical spectrum (range 380-870 nm) of MASTER
OTJ033744.97+723159.0 (Lipunov et al. GCN 21720, GCN2136), on
2017-08-29.54UT with the 2.16-m telescope at Xinglong Station of National
Astronomical Observatories of China (NAOC) on BFOSC (Beijing Faint Object
Spectrograph and Camera).
The spectrum is consistent with a type IIb supernova a few days before the
maximum light, using SN96cb data as the spectral templates.
