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.

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.

Andrew Howell, Curtis McCully, Stefano ValentiGlobal SN ProjectSN Ia0.0191Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190), we find good fits to several Type Ia supernovae 0-2 weeks before maximum light at a redshift of the proposed host galaxy (z=0.019; Falco et al. 1999, PASP, 111, 438 via NED). We measure a Si II velocity of about 16,000 km/s, implying the supernova was discovered soon after explosion, but the absolute magnitude at discovery was about -19, implying it was discovered near maximum light. Together, these could either indicate a young overluminous supernova or a high-velocity supernova at peak.

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.
