Stanek (OSU) ASAS-SN SN II 1 ASAS-SN We 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-18ap shows broad H-alpha and other features characteristic of a Type II SN, also with strong host galaxy contamination. 2018TNSCR..81....1F
