Holoien (Carnegie)ASAS-SNSN Ia1ASAS-SNWe obtained an optical low-resolution spectrum of ASASSN-17rs/AT2017jgm on UT 2018 Jan 13.3 with WFCCD mounted on the du Pont 2.5m telescope at Las Campanas Observatory. The spectrum of ASASSN-17rs is that of a normal Type Ia supernova after maximum light. SNID (Blondin & Tonry 2017) gives a best fit age of +16 days after maximum light.

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.

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-18ap shows broad H-alpha and other features characteristic of a Type II SN, also with strong host galaxy contamination.

Dong (KIAA-PKU)ASAS-SNSN II0.0138361ASAS-SNWe obtained an optical low-resolution spectrum of supernovae candidates on UT 2018 July 15 with WFCCD mounted on the du Pont 2.5m telescope at Las Campanas Observatory. The spectrum of ASASSN-18ou/AT2018dfh is that of a Type II after maximum light. SNID (Blondin & Tonry 2007) gives a best fit age of +8 days after maximum light. The spectrum shows characteristics of normal Type IIP in the plateau phase and Type IIn supernovae (including a narrow P-Cygni profile with v ~ -500 km/s on top of broad FWHM ~ 8000 km/s H-alpha line), with similarities to SN1996L (Benetti et al. 1999, MNRAS, 305, 811).
