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.
