Kostrzewa-Rutkowska (SRON), Ken Chambers, Mark Huber (IfA) ePESSTO+, the advanced Public ESO Spectroscopic Survey for Transient Objects (see Smartt et al. 2015, A&A, 579, 40 http://www.pessto.org ), reports the following spectroscopic classifications of transients in the skymap of GW event s190728q (GCN 25187). Targets were supplied by DECam-GROWTH (GCN 25215). All observations were performed on the ESO New Technology Telescope at La Silla on 2019 07 29, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). Classification spectra and additional details can be obtained from http://www.pessto.org (via WISeREP) and the IAU Transient Name Server. Survey Name | IAU Name | RA (J2000) | Dec (J2000) | Disc.
