Spectra (range 350-760 nm) of supernovae PSN J16283836+3932552 CBAT and PSN J13003230+2758411 CBAT were obtained on May 18, 2015 UT with the F. L. Whipple Observatory 1.5-m telescope (+ FAST). Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) yields the following matches: PSN162838+3932552 matches best with sn2005mz a sn1991bg type Ia at a phase of -7 days before maximum. PSN130032+2758411 matches best with sn2002hu a sn1991T type Ia at a phase of -3 dys before maximum.
