Optical spectra of the supernova candidates ASASSN-16nm/AT2016ijc (ATel #9785), ASASSN-16nn/AT2016ijf (ATel #9785), ASASSN-16no (ATel #9796, #9797), and Gaia16bub/AT2016ice were obtained on UT 2016 November 23-29 with WFCCD mounted on the du Pont 2.5-m telescope at Las Campanas Observatory. We cross-correlated the spectra with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) to help with SN type, phase, and redshift determination. The details of the classifications are as follows:
Name | Spec UT Date | Disc. | Spec. Type | Redshift | Phase | Comments
-----------------------------------------------------------------------------------------------
ASASSN-16nm | Nov. 25.06 | ATel #9785 | SN Ia | 0.030685(host/NED) | +8d |
ASASSN-16nn | Nov. 25.02 | ATel #9785 | SN Ia | 0.0320(SN) | -1d |
ASASSN-16no | Nov. 28.32 | ATel #9796 | SN Ia | 0.020708(host/NED) | -2d |
AT2016ice | Nov. 23.03 | GAIA alerts | CV | 0 | NA | H lines at z=0
