Holoien (Carnegie)ASAS-SNSN Ia1ASAS-SNWe obtained an optical low-resolution spectrum of ASASSN-17rs/AT2017jgm on UT 2018 Jan 13.3 with WFCCD mounted on the du Pont 2.5m telescope at Las Campanas Observatory. The spectrum of ASASSN-17rs is that of a normal Type Ia supernova after maximum light. SNID (Blondin & Tonry 2017) gives a best fit age of +16 days after maximum light.

Stanek (OSU) ASAS-SNSN II1ASAS-SNWe report optical spectroscopic observations of the ASAS-SN transients ASASSN-18am/AT2018gk, ASASN-18ao/AT2018gm, and ASASSN-18ap/AT2018gn (ATel #11178), obtained on UT 2018 Jan 14-16 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-18am has a blue continuum, relatively weak and broad H-alpha (FWHM ~ 5000 km/s), and strong He II in emission (narrow and broad features), consistent with a young Type II SN.

We detect a subtle absorption feature at ~6350 A, which may be caused by C II 6580 at -10,600 km/s. The cool photosphere and possible carbon detection are both notable features of the peculiar SN 2006bt (Foley et al., 2010, ApJ, 708, 1748).

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.
