Stanek (OSU) ASAS-SNSN II1ASAS-SNWe report optical spectroscopic observations of the ASAS-SN transients ASASSN-18am/AT2018gk, ASASN-18ao/AT2018gm, and ASASSN-18ap/AT2018gn (ATel #11178), obtained on UT 2018 Jan 14-16 with FAST (range 3600-7450 Angstroms) mounted on the F. L. Whipple Observatory 1.5-m telescope. We used SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) to aid with the type, phase and redshift determination. ASASSN-18am has a blue continuum, relatively weak and broad H-alpha (FWHM ~ 5000 km/s), and strong He II in emission (narrow and broad features), consistent with a young Type II SN.

We detect a subtle absorption feature at ~6350 A, which may be caused by C II 6580 at -10,600 km/s. The cool photosphere and possible carbon detection are both notable features of the peculiar SN 2006bt (Foley et al., 2010, ApJ, 708, 1748).

Using Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry, 2007, ApJ, 666, 1024), we find reasonable fits to post-peak Type Ia supernovae at the redshift of the host galaxy (z~0.03; The 2MASS Redshift Survey via NED).

The spectrum has very broad lines consistent with a broad-line Type Ic SN around maximum light. SNID (Blondin & Tonry 2007) provides decent fits with spectral templates from the broad-lined SN Ic 2006aj, SN1998bw and SN2007ce.

Stanek (OSU) ASAS-SNSN II0.019051ASAS-SNWe obtained an optical spectrum of ASASSN-18el on UT 2018 Mar 9.5 with OSMOS mounted on the MDM 2.4m telescope at KPNO. The spectrum has a blue continuum with blue weak and broad Balmer lines in emission, consistent with a young Type II SN. The redshift of the host galaxy obtained from nebular emission lines is z=0.01905.

The broad H-alpha p-cygni absorption at ~8000 km/s is very atypical for Type II SNe so late (>150 days) after discovery, but similar to what was seen in the peculiar Type II SN iPTF14hls.
