Stanek (OSU)ASAS-SNSN Ia1ASAS-SNWe report optical spectroscopic observations of ASASSN-16bx/2016ajk (ATel #8712) and ASASSN-16cy/2016ayf (ATel #8801) obtained by S. Frank on UT 2016 March 14-15 with OSMOS (range 398-686 nm) mounted on the MDM 2.4m telescope at KPNO. We used SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) to aid with the type and phase of the SN spectra. ASASSN-16bx is a Type Ia SN about one month after peak brightness (best fit SNID template is SN1999gd at +34 days) and ASASSN-16cy is a normal Type Ia a couple days before maximum (best fit SNID template is SN2002de at -4 days). After correcting the spectrum of ASASSN-16cy for its host galaxy redshift (z=0.034811), we measure a expansion velocity from the Si II 635.5nm line of 12600 km/s.

Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) indicates the following matches.

After correcting the spectra of ASASSN-16dn and ASASSN-16dp by the redshift of their host galaxies, we measure Si II 635.5nm expansion velocities of 10600 km/s and 11900 km/s, respectively.

The source has a blue continuum and broad double-peaked Balmer and He 5875 emission at z~0, with an H-alpha FWHM of about 2400 km/s. This value is high for a CV and suggests the source is observed close to edge-on.

1852016-04-10 03:03:01jlprietoJose Prieto, Ben ShappeeASAS-SNSN Ia0.0237731ASAS-SNWe obtained a medium resolution optical (320-1000nm) spectrum of ASASSN-16ec/AT2016blv (ATel #8915) on UT 2016 April 8.2 with the Magellan Echellette Spectrograph (MagE) mounted on the Magellan 6.5-m Baade telescope at Las Campanas Observatory. The spectrum of ASASSN-16ec/AT2016blv is that of a Type Ia SN after maximum light. After correcting for the redshift of its host galaxy (z=0.023773 from NED), we measure a Si II expansion velocity of ~11800 km/s.

Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin & Tonry 2007, ApJ, 666, 1024) shows that the best match is SN2013ic at -4 days.

Shishkovsky using the Goodman spectrograph on the SOAR 4.1-m telescope on UT 2016 April 16. Classification with SNID (Blondin and Tonry 2007, ApJ, 666, 1024) indicates that the transient is a normal Type Ia supernova roughly 18 days after maximum light, at a redshift of z=0.037 (from the SN lines).

Shappee (Carnegie)ASAS-SNSN Ia1ASAS-SN We report optical spectroscopy (range 370-910 nm) of four supernovae discovered by the All-Sky Automated Survey for Supernovae using the du Pont 2.5-m telescope (+ WFCCD) at Las Campanas Observatory on 2016 Aug. 1-2. We performed a cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024). The spectrum of ASASSN-16ha/AT2016cza is consistent with a Type Ia at +29 days after maximum.

Madore (Carnegie Ob)ASAS-SNSN Ia0.0241ASAS-SNWe report an optical spectrum (range 370-920 nm) of ASASSN-16jq/AT2016fob obtained on UT 2016 Sep. 1.4 with the du Pont 2.5-m telescope (+ WFCCD) at Las Campanas Observatory. We performed a cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024). The spectrum of ASASSN-16jq is that of a normal Type Ia at -1 days before maximum light. The SNID redshift from the SN features is 0.024 +/- 0.005.

Prieto (UDP/MAS)ASAS-SNSN Ia1ASAS-SNAn optical spectrum (range 3600-9000 Angstroms) of ASASSN-16km/AT2016ggb was obtained on UT 2016-09-13.3 with the B&C spectrograph mounted on the du Pont 2.5m telescope at Las Campanas Observatory. The spectrum is consistent with a Type Ia around peak heavily contaminated by the host galaxy light. After correcting for the redshift of the host galaxy, we measure a Si II 6355 expansion velocity of ~12000 km/s.

5302016-11-01 05:18:25boseSubhash Bose, on behalf of ASAS-SN teamASAS-SNSN Ia0.0741ASAS-SNThe best match is found with SN 2001ay (the slowly declining supernova with high Si II velocity; Krisciunas et al., 2011, AJ, 142, 74). After correcting redshift, Si II (6355 Angstrom) absorption velocity is found to be about 12,600 km/s. We measure V-band mag=17.7+-0.04 on 2016-10-27 from Sliding Spring 1m telescope of Las Cumbres Observatory and V-band mag=17.8+-0.16 on 2016-10-28 from All Sky Automated Survey for SuperNovae (ASAS-SN), the quadruple 14-cm "Brutus" telescope in Haleakala, Hawaii. It reaches M_V ~ -19.9 based on the best-fit SN redshift (z~0.074), probably overly-luminous for a SN Ia.

The spectrum shows broad (FWHM ~ 10000 km/s) Balmer lines and a blue continuum, consistent with a young Type II SN. From narrow H-alpha and [O III] 5007 lines, we measure a redshift of z=0.0266 for GALEXASC J215436.98-425103.9, the host galaxy of ASASSN-16ml.

Stanek (OSU)ASAS-SNSN Ia1ASAS-SNAn optical spectrum spectrum of ASASSN-16nm/AT2016ijc was obtained on UT 2016 Nov 25.1 with WFCCD mounted on the du Pont 2.5m telescope at LCO. The spectrum shows that ASASSN-16nm is a Type Ia SN after maximum light. We cross-correlated the spectrum with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024). The spectrum of ASASSN-16nm is most consistent with a normal SN Ia at +8 days after maximum light.

Stanek (OSU)ASAS-SNSN Ia0.0321ASAS-SNAn optical spectrum spectrum of ASASSN-16nn/AT2016ijf was obtained on UT 2016 Nov 25.0 with WFCCD mounted on the du Pont 2.5m telescope at LCO. The spectrum shows that ASASSN-16nn is a Type Ia SN at maximum light. We cross-correlated the spectrum with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) and the spectrum of ASASSN-16nn is most consistent with a normal SN Ia at -1 days. The SNID redshift from the SN features is 0.032.
