Stanek (OSU)ASAS-SNSN Ia1ASAS-SNWe report optical spectroscopic observations of the ASASSN-18ar/AT2018hv obtained on UT 2018 Jan 16.14 with FAST (range 3600-7450 Angstroms) mounted on the F. L. Whipple Observatory 1.5-m telescope. We used SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) to aid with the type, phase and redshift determination. ASASSN-18ao is a Type Ia SN around peak with strong host galaxy contamination.

17292018-02-16 09:26:35linatomaLina TomasellaPadova-AsiagoSN II0.0231Padova-AsiagoThe redshift of the host galaxy is reported by Grogin et al. 1998 (ApJS 119, via NED, z=0.023356 +/- 0.000053) and it is confirmed from the measurement of the narrow emission superimposed to the broad Halpha feature. A good match is obtained with the Type II Plateau SN 2007od (Inserra et al. 2010, MNRAS 417, 261) two/three weeks after explosion. Along with the prominent Halpha we identify HeI, Hbeta, Hgamma, Fe II, Sc II, and Ca II H&K lines. From the position of the P-Cygni absorption of the Hbeta line, we infer an expansion velocity of ~8400 km/s for the ejected material.

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).
