7082017-01-11 03:52:19jlprietoN. Morrell, B. ShappeeASAS-SNSN Ia0.02151ASAS-SNWe report optical spectroscopic observation of supernova candidate ASASSN-16pd/2016jab (ATel #9898) using the du Pont 2.5-m telescope (+ WFCCD) at Las Campanas Observatory on UT 2016-12-24.24. The target was discovered by the All-Sky Automated Survey for Supernovae (ASAS-SN; Shappee et al. 2014, ApJ, 788, 48). We used SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) to identify the type and phase of the SN spectra. The spectrum matches normal SN Ia, few days before maximum light. Narrow Halpha emission is visible at z=0.0215. The SNID estimated redshift (z=0.022) is consistent with this value.

6872017-01-04 14:26:43jlprietoJ. L. PrietoASAS-SNSN IIn0.07681ASAS-SNWe report an optical spectroscopic observation of ASASSN-16pp/AT2016jgr (ATel #9927) on UT 2017 Jan 3.03 using the du Pont 2.5-m telescope (+ WFCCD) at Las Campanas Observatory. The spectrum of ASASSN-16pp shows a blue continuum with H Balmer and He I 5876 lines in emission. The lines have a narrow (unresolved) component and an intermediate velocity component (with Gaussian FWHM ~ 2000 km/s) characteristic of a Type IIn SN. We measure a redshift of z=0.0768 from the narrow part of the SN emission lines, which implies an absolute magnitude at discovery of M_V ~ -20.4.

The spectrum is characteristic of a normal SN Ia past peak with strong host galaxy contamination. Using SNID to fit the spectrum, the best fitting template is the normal SN Ia 2005hf at +9 days. After correcting the spectrum for the redshift of the host, we measure a Si II 6355 Angs. velocity of 8000 km/s.
