Cheng (KIAA-PKU) ASAS-SNSN IaASAS-SNWe obtained an optical spectrum (range 3900-6850 Angstroms) of ASASSN-18bk/AT2018kz on UT 2018 Jan 31.4 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 -2 days and redshift consistent with the host galaxy redshift reported in NED.
