We observed two SN candidates (AT 2016emj, AT 2016emb) with the BTA/Scorpio-I on the night of August, 3. Direct images in the V band and long-slit spectra in the range of 3600-7600AA (resolution FWHM = 10A) were obtained. The spectra were cross-correlated with the SNID library (Blondin & Tonry, ApJ, 666, 1024, 2007).
AT 2016emj was observed on August, 3, 18:55--19:26 UT.
The AT 2016emj spectrum best matched to the normal Type Ia SN 1989B, 4 days after the maximum light,
redshifted by z = 0.073 +/- 0.002.
AT 2016emb was observed on August, 3, 19:42--20:33 UT.
The AT 2016emb spectrum best matched to the normal Type Ic SN 1990aa, near the maximum light,
redshifted by z = 0.065 +/- 0.006. Also in the spectrum we detected a series of emission lines (Halpha, [N II], [O II] 3727A/3729A, [O III] 5007A) from the host galaxy, redshifted by z = 0.059.
