TITLE: GCN CIRCULAR NUMBER: 25931 SUBJECT: LIGO/Virgo S190930t: Palomar 200-in DBSP spectroscopy of ZTF19acbwaah DATE: 19/10/03 00:36:54 GMT FROM: Kishalay De at Caltech, GROWTH V. Karambelkar, K. De, J. Van Roestel, M. M. Kasliwal (Caltech) On behalf of the Zwicky Transient Facility (ZTF) and Global Relay of Observatories Watching Transients Happen (GROWTH) collaborations On 2019 Oct 2 UT, we obtained a spectrum of ZTF19acbwaah/AT2019rpp (Stein et al. GCN 25899) with the Double Beam Spectrograph on the Palomar 200-in telescope. The spectrum is consistent with a type Ia supernova at redshift ~0.03 a few weeks after peak.
