Cheng (KIAA-PKU) ASAS-SN SN Ia 1 ASAS-SN We obtained an optical spectrum (range 3900-6850 Angstroms) of ASASSN-18bi/AT2018ko on UT 2018 Jan 31.3 with OSMOS mounted on the MDM 2.4m telescope at KPNO. The spectrum is that of a normal Type Ia around maximum light. SNID (Blondin & Tonry 2007) give a best-fit age of -1 days and redshift consistent with the host galaxy redshift reported in NED. 2018TNSCR.146....1P
