There is also a clear carbon notch (at CII 6580 Angstroms) in the spectrum.

Using Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry, 2007, ApJ, 666, 1024), we find reasonable fits to post-peak Type Ia supernovae at the redshift of the host galaxy (z~0.03; The 2MASS Redshift Survey via NED).

Stanek (OSU)ASAS-SNSN Ic-BL0.0184691ASAS-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.

17632018-03-06 19:21:14iairIair Arcavi, Griffin Hosseinzadeh, Daichi Hiramatsu, Curtis McCully, D. Andrew Howell, Jaime Burke (UCSB/LCO)Global SN ProjectSN II0.0029791Global SN ProjectWe report a FLOYDS spectrum obtained on 2018-03-06.4 UT with the robotic FLOYDS instrument mounted on the Las Cumbres Observatory 2-meter telescope on Haleakala, Hawai'i, in order to correct a previous classification of this object as a Type Ia-CSM supernova. The added resolution of the FLOYDS data compared to the spectrum reported previously clearly reveals the presence of narrow Balmer H emission lines atop a blue continuum, consistent with a young Type II supernova. Additional narrow emission features include He II 4686A and 5411A, C III 4648A, C IV 5801A, O III 3713A and 3749A, and possibly N III 4640A, similar to those seen in very early "flash spectra" of young Type II supernovae (e.g. Gal-Yam et al. 2014, Nature, 509, 471; Khazov et al. 2016, ApJ, 818, 3; Hosseinzadeh et al. 2018, arXiv: 1801.00015), and in early spectra of the peculiar Type II SN 1998S (e.g. Shivvers et al. 2015, ApJ, 806, 213). It is therefore still too early to classify this event as a Type IIn supernova (or as any other subcategory of the Type II class).

Stanek (OSU) ASAS-SNSN II0.019051ASAS-SNWe obtained an optical spectrum of ASASSN-18el on UT 2018 Mar 9.5 with OSMOS mounted on the MDM 2.4m telescope at KPNO. The spectrum has a blue continuum with blue weak and broad Balmer lines in emission, consistent with a young Type II SN. The redshift of the host galaxy obtained from nebular emission lines is z=0.01905.
