11082017-08-17 00:47:27DAO_OTSDave BalamDAO_OTSSN Ia0.0331DAO_OTSD. 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.

Andrew Howell, Curtis McCully, Stefano ValentiGlobal SN ProjectSN Ia0.0171Global SN ProjectUsing SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find several good fits to the normal Type Ia supernovae in the week before maximum light at redshifts consistent with that of the proposed host galaxy (z=0.017; Barmby & Huchra 1998, AJ, 115, 6 via NED). The supernova is highly extinguished by its host galaxy, making a more precise phase estimate difficult.
