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.

Stanek (OSU)ASAS-SNSN Ia1ASAS-SNWe obtained an optical spectrum of ASASSN-17pk/AT2017iji on UT 2017 Nov. 21.5 with FAST mounted on the FLWO 1.5m telescope. The spectrum is that of a normal Type Ia caught early. The best fit templates with SNID (Blondin & Tonry 2007) are of normal SN Ia at <~1 week before maximum light After correcting the spectrum for the redshift of the host galaxy (z=0.013493), we measure a Si II 6355 Ang. expansion velocity of 14500 km/s from the minimum of the P-Cygni absorption through.

Pastorello (INAF-OAPd)Padova-AsiagoSN Ia0.0278461Padova-AsiagoThe spectrum resembles that of the normal Type Ia SN 1999ee (Hamuy et al. 2002, AJ, 124, 417) about one week after the B-band maximum. The velocity of the SN ejecta, as inferred from the position of the minimum of the Si II 635.5 nm feature, is about 10800 km/s. The redshift of the host galaxy is from Huchra et al. 2012, ApJS, 199, 26.

16402018-01-15 20:35:31jlprietoJ. L. Prieto (UDP), J. Rich, T. Holoien (Carnegie)ASAS-SNSN Ia1ASAS-SNWe obtained an optical low-resolution spectrum of ASASSN-17rs/AT2017jgm on UT 2018 Jan 13.3 with WFCCD mounted on the du Pont 2.5m telescope at Las Campanas Observatory. The spectrum of ASASSN-17rs is that of a normal Type Ia supernova after maximum light. SNID (Blondin & Tonry 2017) gives a best fit age of +16 days after maximum light.
