Dave Balam report/s a classification of object: SN 2017gav

Type: SN Ia
Redshift: 0.033

Remarks: D. D. Balam, Dominion Astrophysical Observatory, National Research Council of Canada, K. Thanjavur (University of Victoria) and E. Hsiao, Florida State University report that a spectrogram (range 390-710 nm, resolution 0.3 nm) of SN 2017gav obtained on Aug. 16.25 UT with the 1.82-m Plaskett Telescope of the National Research Council of Canada, shows it to be a normal type Ia supernova near maximum light. Cross- correlation with a library of supernova spectra using the "Supernova Identification" code (Blondin and Tonry 2007, Ap.J. 666,1024) suggests that SN 2017gav is most similar to the normal type-Ia supernova at maximum light. Our solution yields a red shift of 0.033.
