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.

Stanek (OSU)ASAS-SNSN Ia1ASAS-SNWe obtained an optical spectrum of ASASSN-18ef on UT 2018 Mar 4.4 with OSMOS mounted on the MDM 2.4m telescope at KPNO. The spectrum is that of a normal SN Ia around maximum light. The best fit template from SNID (Blondin & Tonry 2007) is the Type Ia 2005mc at -2.2 days.
