We can see such emission lines as  Balmer series(H_alpha,H_beta.H_gamma), He I (4472, 5876, 6678, 7075), He II (4686, 5412), N III (4641), C III (4647) and [O III] (5007) on the our spectrum.
We also find out that the FWHM of H_alpha is approximately 800 km/s.
Additionally, our results of multi-color photometry are B = 10.69(1), V = 9.89(1), Rc = 8.90(1) and y = 9.90(1). Comparioson star used is TYC2681-464-1 (V=8.60, B-V=0.35).
