Stanek (OSU) ASAS-SN SN Ic-BL 0.018469 1 Add ASAS-SN We obtained an optical spectrum of ASASSN-18dr on UT 2018 Mar 6.35 with OSMOS mounted on the MDM 2.4m telescope at KPNO. 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. 2018TNSCR.306....1P
