We observed PS19qo (Smith et al., GCN 24210) a potential counterpart to the gravitational wave trigger S190425z (GCN 24168), under the advanced Public ESO Spectroscopic Survey for Transient Objects (ePESSTO+; see Smartt et al. 2015, A&A, 579, 40 http://www.pessto.org). The observations were performed on the ESO New Technology Telescope at La Silla with the EFOSC2 instrument.

This candidate was chosen because of its apparent association with a cataloged galaxy at 199 Mpc. The NTT spectrum gives a good match to normal Type II SN at z=0.057.
