We obtained spectra of ATLAS16ahj/AT 2016bey and ATLAS16agv/AT 2016bfc (ATel #8839) on 2016 March 19.5 UT with the robotic FLOYDS instrument mounted on the LCOGT 2-meter telescope on Haleakala, Hawai'i.
Using Superfit (Howell et al. 2005, ApJ, 634, 119), we find a good fit for ATLAS16ahj/AT 2016bey to the normal Type Ia SN 1994D 5 days before maximum light at the redshift of the proposed host galaxy (z=0.073; SDSS DR4, via NED).
Using SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find good fits for ATLAS16agv/AT 2016bfc to several normal Type Ia supernovae a few days before maximum light at redshifts around z=0.05.
The spectra are available on the Transient Name Server for both AT 2016bey and AT 2016bfc.
