Stanek (OSU)ASAS-SNSN Ic-BL0.018469ASAS-SNWe 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.
