We obtained two optical spectra of SN 2016aqt, discovered by R. Gagliano, J. Newton, R. Post, and T. Puckett (POSS), on 2016 March 2.7 UT with the Xinglong 2.16-m telescope (China) and on 2016 March 4.7 UT with the robotic FLOYDS instrument mounted on the LCOGT 2-meter telescope in Siding Spring (Australia). Using some spectral fitting tools such as the SNID (Blondin and Tonry, 2007, Ap.J., 666, 1024) and the Superfit (Howell et al. 2005, ApJ, 634, 119), we find these spectra are similar to that of some overluminous Type Ia supernovae like SN 1998es and SN 1999aa within a few days from the maximum light. At a redshift of the proposed host galaxy (z=0.050; SDSS DR6 via NED), the reported discovery magnitude corresponds to an absolute magnitude of about -20.1. The spectra and discovery details are available on the Transient Name Server.
